Vacuum low-temperature drying box for preparing powder essence

Abstract

The invention discloses a vacuum low-temperature drying box for preparing powder essence. The vacuum low-temperature drying box comprises a box body, a motor is fixedly installed on the box body, theoutput end of the motor is fixedly connected with a rotary disc through a telescopic connecting rod 3, a filter screen is fixedly installed on the rotary disc, a limiting ring is fixedly installed onthe rotary disc, a plurality of sliding grooves are evenly formed in the box body, a sliding block is connected in each sliding groove in a sliding mode, each sliding block is provided with an annulargroove, and a connecting ring is fixedly installed on the limiting ring and connected among the multiple annular grooves in a sliding mode. The vacuum low-temperature drying box for preparing powderessence has the advantages that in the powder essence drying process, caked or condensed powder essence in the box body can be decomposed more quickly through centrifugal force and vibration force, the distribution uniformity degree of the caked or condensed powder essence in the box body can be improved, water vapor in the caked or condensed powder essence can be sublimated better, the drying efficiency can be improved to a certain degree, and the drying effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of powder essence preparation, in particular to a vacuum low-temperature drying oven for preparing powder essence. Background technique [0002] Flavor refers to a mixture of various spices prepared by artificially blending natural flavors or artificial flavors in appropriate proportions. It is mainly used in food and other fields. Powdered flavors are dehydrated and dried products. [0003] The preparation of powder flavor is usually carried out in a vacuum low-temperature drying box. When the vacuum low-temperature drying box is working, the gas and water vapor in the box are drawn out through the operation of the vacuum pump on it. However, the existing powder flavors are usually in the vacuum low-temperature drying box. static state, so the extraction rate of water vapor in it is relatively low, and if the powder essence in the frozen state is dried, because the water in it condenses into solid ice, the ...

[0003] The preparation of powder flavor is usually carried out in a vacuum low-temperature drying box. When the vacuum low-temperature drying box is working, the gas and water vapor in the box are drawn out through the operation of the vacuum pump on it. However, the existing powder flavors are usually in the vacuum low-temperature drying box. static state, so the extraction rate of water vapor in it is relatively low, and if the powder essence in the frozen state is dried, because the water in it condenses into solid ice, the sublimation rate will be further reduced at this time, seriously affecting the drying rate
