Introduction to silkworm：

  The body of the silkworm is clearly segmented, and the two body segments protrude into warty feet with bristles for movement. It is about 10 cm long. Silkworms are the best food for fish, shrimps and crabs, so they are highly valued by the aquaculture industry. Silkworm has medicinal and therapeutic value, and has been used as food and nutritional health products.

Silkworm processing steps:

  Remove impurities from the prepared silkworms, rinse them with sea water, and drain the excess water. The cleaning process cannot be omitted, otherwise, the colored sludge will contaminate the silkworm during the salting and preservation process, and change the color of the silkworm body surface. Mix the drained silkworm with large grains of salt and spread it flat on multiple layers of old newspapers, then roll up the newspaper and stand in a dark, well-drained place to drain the water from the salted silkworm. Note that the water and slimy body fluids from the silkworms should flow out of the paper roll in time, and they should not be nested in bait bags, otherwise it will cause the rot of the silkworms.
  After two hours of salting, the moisture in the body of the silkworm is basically removed. At this time, the silkworm should be spread again on a thick, absorbent, dry cloth and rolled tightly. After the outer layer is tightly wrapped, use a heavy object on a flat and dry ground. After being pressed for one to two hours, the residual moisture on the surface of the silkworm will be fully absorbed by the dry cloth again. Open the cloth bag, the silkworm bait is glued together in a cake shape, use a small handful of refined salt as a release agent, shake the bait cake one by one by hand and mix well, change the dry cloth and wrap it in a plastic bag and seal it in the freezer of the refrigerator.

Silkworm drying process：

  Select fresh, fat and high-quality live silkworms, and go through the procedures of removing mud, salt water storage, spitting, draining water, and steaming in the basket. Put the steamed silkworms into the material truck tray and send them to the heat pump for drying. Room, the drying temperature is set to 50°C-60°C, the drying time is 12 hours, the drying process is continuous to dehumidify, the moisture content after drying is below 10%, and the dried silkworm has a light yellow and pure taste. With its high-quality fragrant fragrance, it can be widely used in scientific research fields such as food, medicine, beauty, feed, and additives.
 

Recommendation of silkworm 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.
