Shrimp, fish drying, seafood dryer

here are various kinds of shrimps, such as prawns, prawns, Pipa prawns, lobsters, etc.; freshwater shrimps such as green shrimp, river shrimp, grass shrimp, crayfish, etc.; and brackish water shrimp such as white shrimp. Shrimp has delicious taste, rich nutrition and high protein content. The edible part of shrimp accounts for about 16-20% of protein. It is also rich in minerals (such as calcium, phosphorus, iron, etc.) and iodine, which is very beneficial to human health. According to scientific analysis, the muscle fiber of shrimp is relatively thin, and its meat is tender, soft and easy to digest. It is an excellent food for people who are weak and need to be nursed after illness. As a kind of real nutrition food, dried prawns are delicious and durable to be stored, which are popular among consumers. With the advent of the new era, the use of shrimp heat pump dryer to replace the traditional sun, put an end to the sun by mosquitoes, no longer affected by bad weather, while reducing human and material resources, improve the quality of dried shrimp, reduce costs, let some seafood processing plants taste the sweetness. This paper briefly introduces the core steps of drying delicious dried shrimp with shrimp dryer.

Shrimp processing process steps:

After removing the sediment and impurities, the prepared prawns should be boiled or steamed in time, and salt accounting for 6-8% of the weight of the shrimp should be sprinkled. The steaming time is that the color of the shrimp changes from green white to red. At this time, the shrimp is easy to shelled.

Step 2: drying

1. The steamed shrimp can be dried with shell or shelled for drying. Drain the boiled prawns, evenly spread them on the drying plate, load them into the material truck, and then send them to the shrimp drying room.

2. According to the different varieties of shrimp, the temperature of the intelligent control system of the dryer should be set at 50 ℃ ~ 70 ℃ medium high temperature. The time is about 4 hours, and the moisture content is 18%. In the drying process, it is generally required to have a slightly larger circulating air volume and higher wind speed to avoid water vapor staying on the dried shrimp surface. The control points are to inhibit the growth of bacteria and keep the color of dried shrimp and shrimp.

3. According to the above drying steps, dried shrimps dried with shrimp dryer have complete shape, neat appearance, natural color, light yellow and light red luster, plump meat, curved shrimp body, and unique natural flavor.

Step 3: Inspection and packaging

The dried prawns are cooled to room temperature and packed in different grades. Store in ventilated and dry warehouse or freezer according to factory or customer requirements.

Features of Jinkai heat pump dryer

1. No pollution. In the drying process, the drying medium is closed and circulates in it, and there is no pollution caused by material dust, volatile substances and peculiar smell when the drying waste gas is discharged to the environment; the waste heat in the drying chamber exhaust is directly recovered by the heat pump to heat the cold dry air, and there is no heat pollution of the unit to the environment.

2. Good drying quality. The closed circulation of drying medium can avoid the impurity pollution caused by gas exchange with the outside world, which is particularly important for food, medicine or biological products.

3. Convenient temperature and humidity control. Set the temperature and humidity by the control panel, which can be accurate to 1 degree. For some materials (such as wood, etc.) with high temperature or humidity requirements, the effect of texture and appearance is outstanding.

4. High energy efficiency. Heat pump has a more efficient heating capacity than direct energy supply, which is manifested in its heating energy consumption ratio (COP) is always higher than 1. In the heat pump drying system, in addition to the electrical energy from the compressor, the heat energy of the drying hot air also comes from the heat energy contained in the drying exhaust gas absorbed by the evaporator. Compared with steam drying, it can save 40% - 70% energy.

5. High efficiency and energy saving, low operation cost. The operating cost of heat pump dryer is only 30% of the electric heating dryer, 40% of the fuel oil dryer and 60% of the coal-fired dryer. Moreover, the heat pump dryer does not need to consume any fuel, thus saving the cost of transportation and storage of fuel, and the economic benefit is more obvious.

6. Safety and environmental protection. Heat pump dryer is to transfer the heat in the air to the drying room to achieve the purpose of drying, so it only consumes the electricity to carry the heat. There is no need to consume other fuels, that is, to avoid safety and environmental pollution problems in the transportation and storage of fuels. The operation process does not produce any pollutants.

7. Good drying effect. Because the heat pump dryer adopts automatic control, the operation state of the unit can be adjusted automatically according to the setting mode, with stable temperature rise, uniform temperature and less temperature fluctuation, so as to avoid the impact of human factors on the drying quality during the operation of the fuel dryer.

8. Heat pump dryer is widely used in materials. Controlled drying temperature is 8-75 ℃. In this range, most materials are dried, such as papermaking, printing, electroplating, tobacco, slime, mosquito repellent incense, textiles, leather, tea, candy, food, ceramics, wood, Chinese medicinal materials, dried fruits, fish, cured meat, marine treasures, high protein food, all kinds of seeds, edible fungi, vegetables, fruits, chips, ginger, peanut, aquatic products Products and thermal chemical materials
