The variegated pupa and clam's nutrients consist of variegated crickets. Habits: dioecious, in vitro fertilized, spawning period from September to November, very adaptable to temperature and salinity, inhabiting the intertidal mudflats along the estuary coast or inner bay. , food diatoms, benthic diatoms, organic debris and so on.
Economic value: 100 grams of fresh meat contains 8.1 grams of protein, 0.4 grams of fat, 2 grams of carbohydrates, and 0-6 grams of inorganic salts. Delicious taste, high economic value and nutritional value.
Wen Hao living habits: reproductive period from June to October. China's coastal areas are distributed, living in the intertidal zone and shallow sea surface of the fine sand surface, due to changes in water temperature have mobile habits, whip algae, Chaetoceros, Heterocallis and so on. Dandong area now uses cultured shrimp ponds to culture the clams, so that individuals grow evenly in size, while shrimp can be renewed in the pool.
Economic value: 100 grams of fresh meat with protein 10 to 4 grams, fat 0 to 9 grams, carbohydrates 1 to 9 grams, 2 to 6 grams of inorganic salts. Wenyu is the top grade of Chinese wolfberry, tender meat, delicious and nutritious, can be eaten fresh, can also process dried products and canned food. The oyster shell is the attachment base for artificial breeding of seaweed and can also be used as high standard cement raw material.
The nutrient composition of variegated quail and clam was due to muscle fiber and connective tissue, and its weight composition ratio differed depending on the size of shellfish, shellfish or larvae, fat lean, season, before and after spawning, and sex.
From a nutritional point of view, proteins are classified into complete proteins and incomplete proteins. Complete proteins contain eight essential amino acids, whereas the lack of one of them is incomplete. The protein contained in variegated clams and clams is complete protein. It is worth mentioning that the iodine content of shellfish is 10 times higher than that of beef, milk, eggs and wheat. In addition, shellfish also contains vitamins A, D, K, B, B2, B12, etc., its nutritional value in a certain degree than animal meat, but also has medicinal and health care value. Although its shell is an inedible part, mainly containing calcium and nacre, but it is an important raw material in the industrial and pharmaceutical fields, Wenzhou shells can be processed into a variety of advanced works of art, its economic value even exceeds its shellfish.
The processing and packaging of mottled maggots and clams for the living organisms are increasingly in demand in the Japanese market. Due to its ability to adapt to environmental conditions, mottled crickets and clams can survive for hours or even days without death. The body cavity contains a certain amount of seawater, which can play a regulatory role after fishing. This will bring certain benefits for storage and shipping, but it will directly affect the quality of the shellfish sorting time, packaging, transportation and other factors. In the Dandong area, Wenlan currently uses shrimp pond culture. Therefore, the following links are discussed:
The seawater in the shrimp pond is drained and the water is pumped out into the large nylon net. The fish is washed up and down in another shrimp pond with seawater. After washing away the impurities on the surface of the shell, it is piled up in Bashang. The clean canvas, immediately sorting, according to 3cm-4cm4cm-5cm5cm-6cm6cm more than four specifications of sorting; less than 3cm, dead cockroaches, split clams, broken shell clams separately stored. After sorting, woven bags or sacks are used to pack 21kg bags in one pound, and are loaded with twine. Generally, one shrimp pond can produce 14-16 tons. Since the outbreak season is autumn and summer, car transportation should be carried at night. Customs shipment. Live mottlers can also be transported to the dock by ship. After washing with seawater, the concrete floor is cleaned at the pier. The sorting level is the same as above. However, regardless of the means of transport used to transport, there should be cover, anti-sun, anti-rain and the measures and methods. The variegated clams and clams that are less than 3cm in size are transported to the canning workshop of the factory, and the cracked clams are transported to the baking workshop, and the crushing shells are transported to the crushing workshop.
The original juice whole shell vacuum packaging less than 3cm specifications of variegated quail, Wenyu shipped to the factory canned workshop, washed again with tap water three times, weighed, according to 5 or 6 into the high temperature resistant composite film bag, net weight 30g. Packed in a hot-press vacuum packaging machine and steamed with a steamer. The temperature is controlled at 125°C for 8 minutes. At the same time, the pressure is 1-3kg/cm2 in the sterilizing pot. After the sterilization, the cooling water is used to reduce the pressure. After the temperature is reduced to room temperature, remove and wash. After drying, press 12 bags per small box, 4 small boxes for each big carton, and put it in cold storage.
The product is characterized by the fact that it can be stored for six months under normal temperature, and it can be packaged and refined, and it is convenient to eat. The taste is maintained in the flavor of the original juice. It is welcomed by customers and its economic value far exceeds that of the raw material itself.
Roasted dried products are transported to the roasting workshop for export of uneatable stew meat selected by rip and frozen processing workshops. The rip wounds are first peeled off the shells. Take the meat program. After taking the meat, wash it with running water, and then sort out the more complete mutton meat and broken meat. Put the more complete mutton meat on the basis of 5 grains and 7 grains in two specifications and wear it with a bamboo worm. Rinse once with 50ppm sodium hypochlorite. Soaked with a certain concentration of sorbic acid for 10 minutes. The washing and immersing of the crushed pterygium were the same as above, without stringing. First, skewer and minced meat are placed neatly on the steel mesh. Then, the steel mesh is placed on the steel frame of the cart and pushed into the tunnel drying room. The temperature is controlled at about 20°C, that is, the air is dried at low temperature and dried. In half an hour, a car is introduced every 7-10 minutes. The entire drying room can be designed to place 12-13 small carts, each containing 100 kilograms of meat. Drying the finished product is done with a large plastic bucket for 3 hours and then baked in a chain oven for 3 minutes. The temperature of the oven is 121°C. Due to the small size of the eel, the baking time is long and easy to burn. After baking, weigh and package. Because the product is a semi-dry product, it should be put into cold storage. In addition, after the raw materials are washed, some seasonings may be soaked according to local customs to prepare spiced, spicy, sweet, multi-flavored roast products.
Frozen product full-shell frozen products will be cleaned with fresh mottled clams and clams, respectively, with seawater to wash the sediment on the surface of the shell, put it into the basket, and then put it into the holding pool to spit it out. The bottom of the pool should be padded with wood. In and out of water pipes, long running water, water temperature is controlled at 7-15 °C, not more than 17 °C, temporary holding pool must have sun-fighting facilities, air circulation, spit sand time is 48 hours, remove and wash, according to export standard specifications; select The smashed and smashed rakes were transported to the roasting workshop; the small stencils that did not meet the export standards were shipped to the canning workshop; and the crushing smashers were sent to the smashing workshop. Sorting and sorting qualified moths and clams are bagged and kept in their original state. They are sent to the quick-freezing room for freezing. The frozen product center temperature should reach 15°C and the quick-freezing time should not exceed 12 hours.
Freeze fresh products, and clean the live oysters and clams with seawater and place them in a sieve. When taking the meat, press the mallet on the plate with your left hand, hold the knife in the right hand, slowly insert the knife into the lower shell from the front of the bowl, cut the muscle of the closed shell along the inner surface of the bottom shell, open the shell, and then cut off the other A shell of the adductor muscle, remove the fat. Note that when inserting the blade, do not crush the shell and keep the two shells connected. The shell of the clam shell should be sent to the processing and processing workshop for processing and export. After removing the mutton meat, it shall be sorted according to the individual size after washing, and the weighing shall be carried out. Each specification shall meet the export standard and 1 kilogram for each plate. The plate shall be transported into the quick freezing room for freezing, and the freezing time shall not exceed 12 hours. To the center temperature is below 15 °C, out of the library, into the shower to take off, the shower room temperature should be controlled below 4 °C, after the plate off the ice, the water temperature of the ice coating should be controlled at about 4 °C, often change the water The ice-plating time is 5 to 10 seconds. It is taken out into a polyethylene plastic bag, and then loaded into a large carton. Each carton is loaded with 12 plates. After packaging, it enters the cold storage room and is placed in batches according to the inspection requirements.
Bleaching monomer quick-frozen product This product is basically the same as raw and frozen product processing operation process. The difference is that after opening the variegated meat and squid meat, it is placed in a small sieve, and is heated at 80°C-90°C for 30 seconds. Take out the water and cool it down. After 10 minutes of draining, freeze it on a single quick-freezer to bring its center temperature to ?15°C, weigh it, and put it in a small sieve for every 2 kg. After the screen is filled with water, it will be bagged. The carton packs 6 bags and packs them into stock. The purpose of bleaching soup is to remove the surface mucus from the raw meat and make the raw meat surface with a certain hardness, which is convenient for quick freezing of the monomer.
Block frozen boiled oyster meat Because the frozen boiled oyster meat is sold in Japan in a low price, but it is not easy to accept in China, so it does not involve frozen boiled oyster meat.
A. Temporary resuscitation: Disperse the impurities on the surface of the shells with fresh seawater and fill them with perforated plastic sieves. Each sieve contains 8 kg. The thickness of the bowl is preferably about 6 cm. The plastic sieve is then used. In large cement pool, the bottom of the pool should be filled with wood, with water inlet and outlet pipes, to maintain a long flow of water, water depth of 40cm or so, water temperature 7-15 °C is appropriate, you can set a number of large cement pool, temporary pool should be covered Sun facilities can be kept for 48 hours.
B. Cooking: After being out of the tank, clean it again and put it in a steamer with a volume of 0 to 5 m3. The steamer has steam inlets and outlets. There is a stainless steel sealing cover on the top 45. - "China Fisheries" 1999, issue 9 There is a flapper at the head and the bottom of the car is “V†shaped. The front of the bottom of the car box is low from the ground, and the back is high above the ground. After being filled with variegated clams, it is connected with the steam pipe of the boiler. The steam valve is opened and steam is variegated. After 8 minutes, steam is turned off. Valve, remove steam tube.
C. Discharge the variegated sap. Before pushing the cooking cart to the variegated sap collection box, lift the cutting board about 5 cm high so that the variegated simmered cooking juice flows into the collection box according to its own weight.
D. Shelling: After removing the juice, push the cooking car to the bucket elevator, pull out all the inserts, pour the cooked file into the feed, and drop it into the hopper of the bucket elevator. , Lifted by a bucket elevator to the feed end of the first screening section of the reciprocating separator-type shelling machine, and dropped onto the shelling sieve through the feeding hopper. The working frequency of the sieve body driven by the crankshaft is 480 times per minute. For 30mm horizontal reciprocating motion. The rake is automatically spread out under the vibration of the screen body so as to excite the meat from the shell. The escaping meat passes through the mesh slot and falls onto the chain plate type meat conveying machine to output. A small amount of non-separated quail meat is picked out manually. , can produce 7-8 tons per hour.
E, washing; The meat is put into a plastic sieve, placed in a stainless steel tank, the tank volume is 2m3, rectangular, the bottom of the tank is equipped with a hole water pipe, long running water, and make the water in the tank turn up, play two roles of cleaning and cooling Every 10 minutes after the vote, the material will be taken once.
F. Sorting: Pour the dumplings on a stainless steel cutting board. There must be a tap on the case, in accordance with five specifications per 300 pounds, 301-500 grains, 501-700 grains, 701-1000 grains, 1001 grains or more. Select, namely, XL, L, M, S, and SS. And put each size in a plastic sieve.
G. Secondary cleaning: The plastic sieve containing the well-chosen meat is washed by two flow sinks. The two sinks are one high and one low, and the water flows from the high tank to the low tank. The tank should be washed in a low tank. Wash it first and then wash it in the trough again.
H. Drainage Weighing: Wash the good quail meat on a stainless steel frame with a height of 40cm and drain it for 10 minutes. Weigh it on a scale, place a plate for each 2kg, and put in a pair of specification labels.
I. Swing plate, drowning water: Take a clean plate, put a label face down, then put the well-known quail meat, use another plate bottom flattened, and paste a label, every five The plates were stacked together and poured into clean water to make the five plates upside down. After drowning for 5 minutes, they were flipped over and placed on the flatbed carts.
J. Quick-freezing: Push the meatballs into the quick-freezing room and put them on the steel rack. Inject 2/3 water first, and then freeze the water for 2 hours before injecting water once. The purpose is to prevent the water from being filled for the first time and make the meat and The label floats, but do not inject too much water for the second time.
The product's delivery, removal, ice-plating, packaging, storage, batch placement and other processes are the same as those for raw frozen product processing.
Monolithic frozen boiled quail meat This product processing operation process and block broiled variegated mutton meat processing process is basically the same, but after the drain, directly on the monomer freezer, so that the center temperature reached ? 15 °C, then press each small sieve 2kg After weighing, use a small sieve to put water on the ice-plated clothes, put the plastic bags, and put them into large carton packaging. Each paper carton packs 6 bags and puts them in storage.
The oyster husk processing will be used to transport the conjoined oyster shells of the frozen frozen oyster meat to the craftwork processing room, carefully selecting the complete oyster shells, grading and washing according to the specifications, and placing them in the stencils.
