Embodiment 1

[0030] Feeding: put the food to be dried on the drying bed through the hopper; air cooling: turn on the fan to perform preliminary air cooling on the food, and form convective air to pass through the surface of the food for air cooling to keep the moisture inside the food at 90%; high temperature Baking: After the air cooling is completed, turn on the heater and adjust the temperature to a high-temperature heating block to keep the moisture inside the food at 40%; Spreading: After taking out the food, spread the food evenly on the drying rack to make the food The internal moisture is kept at 30%, and the distance between foods is kept at 5-10cm; low-temperature baking: put the food in a low-temperature baking oven, and adjust the temperature to low-temperature insulation to keep the moisture inside the food at 5%; Material: Put the dried food into a packaging bag and seal it.

Embodiment 2

[0032] In embodiment one, add following operation:

[0033] The time for air cooling in step 2 is controlled at 30-35min.

[0034] Feeding: put the food to be dried on the drying bed through the hopper; air cooling: turn on the fan to perform preliminary air cooling on the food, and form convective air to pass through the surface of the food for air cooling to keep the moisture inside the food at 90%; high temperature Baking: After the air cooling is completed, turn on the heater and adjust the temperature to a high-temperature heating block to keep the moisture inside the food at 40%; Spreading: After taking out the food, spread the food evenly on the drying rack to make the food The internal moisture is kept at 30%, and the distance between foods is kept at 5-10cm; low-temperature baking: put the food in a low-temperature baking oven, and adjust the temperature to low-temperature insulation to keep the moisture inside the food at 5%; Material: Put the dried food into a pack...

Embodiment 3

[0036] In embodiment two, add following operation:

[0037] The heater used in step 3 is an air energy heat pump dryer, the baking time is 25-45min, and the baking temperature is controlled within the range of 70-90°C.

[0038] Feeding: put the food to be dried on the drying bed through the hopper; air cooling: turn on the fan to perform preliminary air cooling on the food, and form convective air to pass through the surface of the food for air cooling to keep the moisture inside the food at 90%; high temperature Baking: After the air cooling is completed, turn on the heater and adjust the temperature to a high-temperature heating block to keep the moisture inside the food at 40%; Spreading: After taking out the food, spread the food evenly on the drying rack to make the food The internal moisture is kept at 30%, and the distance between foods is kept at 5-10cm; low-temperature baking: put the food in a low-temperature baking oven, and adjust the temperature to low-temperature...

Abstract

The present invention discloses a highly efficient drying technology used for food research and development. The highly efficient drying technology comprises the following steps: material feeding is conducted: food to be dried is placed on a drying bed through a material hopper; air cooling is conducted: a fan is turned on to conduct preliminary air cooling on the food, convective air is formed and passes through the surface of the food to conduct the air cooling, and the moisture inside the food is maintained at 90%; and high-temperature baking is conducted: after the air cooling is completed, a heater is turned on, temperature is adjusted to a high temperature heating level to enable the moisture inside the food to maintain at 40%. The highly efficient drying technology solves problems that a food drying technology in the prior art is still not perfect, too cumbersome, reduced in food drying efficiency, and easily causes food mildew due to incomplete drying, shortens food edible shelf life, and at the same time also has a serious impact on economy of a food factory. The highly efficient drying technology used for the food research and development has an advantage of high drying efficiency and is worthy of promotion and use.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to an efficient drying process for food research and development. Background technique [0002] Agricultural and sideline food processing industry refers to grain grinding, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, and vegetables, fruits and nuts directly using agricultural, forestry, animal husbandry and fishery products as raw materials Food processing activities, in simple terms, are to put edible things through certain procedures to make them more delicious or beneficial, and to artificially process raw grains or other raw materials to form a new form of food that can be eaten directly. This process is food processing, which is a type of generalized agricultural product processing industry. [0003] Food is the most important thing for the people. With the rapid growth of China's food industry, the...
