Introduction to cuttlefish：

  Cuttlefish is a shellfish, belonging to the mollusk, Squididae. When a cuttlefish encounters a powerful enemy, it will use inkjet as a method of escape and wait for an opportunity to leave. There are small pigment sacs in its skin, which will change color and size with changes in "mood".

Cuttlefish processing steps：

1. Material selection
Cuttlefish should be sorted according to size and freshness before caesarean section to facilitate uniform dryness during the drying process and facilitate the classification and packaging of finished products.
2. Cut
Hold the fish's back with the fish's belly up, pinch slightly to make the abdomen protrude, hold the knife from the upper end of the abdomen and insert the cut or cut straight to the tail gland. When cutting to the nearly glandular hole, the knife handle should be lowered so that the knife edge is upward and gently cut through to prevent the ink sac from being cut. After the abdominal cavity is opened, the head and neck are straightened immediately, and the incision is made from the center of the water pipe at the top of the abdomen to the center of the wrist of the head. When cutting into the mouth of the fish, cut the blade diagonally to the left and right to cut the eyeball, allowing the water in the eyeball to drain out for drying. And use a horizontal knife to cut the junction between the mouth and the esophagus to facilitate drying and removal of internal organs. The cutting edge should be straight and symmetrical. The first knife should leave a little distance near the gland hole. Otherwise, it will be easily curled in the sun, water will deteriorate, and the drying will be slow.
3. In addition to internal organs
Before removing the internal organs, remove the ink sac and gently pull up the ink sac gland. If the ink sac is slightly forward, pull it back, and then gently pull it forward, and then carefully remove the ink sac to stop the ink. Pollution of white meat noodles, affecting washing and appearance. When removing the internal organs, start from the tail end, tear it to the head, and tear it to the vicinity of the gills. Use your fingernails to peel off the gills and liver attached to the muscles.
4. Washing
Put the eviscerated cuttlefish in a fish basket, each basket is about 5 kg, and place it in the sea water transfer basket to soak and wash away the ink and dirt adhering to the cuttlefish body.

Cuttlefish drying process：

  Drying is generally required to be carried out at a relatively low temperature, and the temperature is set to about 40°C. In order to avoid the temperature is too high, the protein denaturation, destroy the quality of drying. At the same time, avoid rapid drying, which will cause the cuttlefish surface to crust and form false drying. In the heat pump drying room, the negative pressure fan is used to increase the circulating air volume and wind speed in the drying room, and the drying is uniform and slow. While maintaining a large circulating air volume and a high wind speed, the cuttlefish can fully contact the air, and the water vapor evaporated from the cuttlefish is taken away under the action of the circulating wind, and then the water vapor is condensed and filtered out by the unit to be discharged out of the room.
Since cuttlefish are not only high in water content, but also in fat and grease, cuttlefish drying should avoid moisture staying on the surface of the squid body, causing poor moisture drainage and causing bacteria to grow. Usually, the feed amount of wet cuttlefish is 4-5 jin, and you can get 1 jin of dried cuttlefish after drying. The dried cuttlefish has good quality, bright color, and can maintain the best results.

Recommendation of cuttlefish dryer/drying machine

Commercial 100-3000kg/h large amount of dehydration wide application and easy operation

  Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.

  Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
