Vacuum low temperature drying oven for the preparation of powder essence

Abstract

The invention discloses a vacuum low-temperature drying box for preparing powder essence, which includes a box body, a motor is fixedly installed on the box body, and the output end of the motor is fixedly connected with a turntable through a telescopic connecting rod 3, and a turntable is fixedly installed on the turntable There is a filter screen, a limit ring is fixedly installed on the turntable, a plurality of chutes are uniformly arranged in the box, and a slider is slidably connected to each chute, and each slider is provided with a ring grooves, and a connecting ring is fixedly installed on the limiting ring, and the connecting ring is slidably connected between a plurality of annular grooves. The advantage is that: in the process of drying the powder essence, the present invention can utilize centrifugal force and vibration force to decompose the agglomerated or coagulated powder essence in the box faster, and can improve the uniformity of its distribution in the box, which is convenient for water in the box. The steam is better sublimated, which can improve the drying efficiency to a certain extent and ensure the drying effect.

Description

Technical field [0001] The present invention relates to the field of powder flavor preparation technology, in particular to a vacuum low temperature drying chamber for the preparation of powder flavors. Background [0002] Flavor refers to a mixture of a variety of flavors prepared by artificial natural flavors or artificial flavors in an appropriate proportion, mainly used in food and other fields, of which powder flavor is the product of dehydration and drying of flavors. [0003] The preparation of powder flavor is usually carried out in the vacuum low temperature drying box, when the vacuum low temperature drying box works, the gas and water vapor in the box are extracted through the operation of the vacuum pump on it, but the existing powder fragrance is usually in a static state in the vacuum low temperature drying box, so the extraction rate of the water vapor in the vacuum is relatively low, and if the powder flavor in the frozen state is dried, because the water in it co...

Problems solved by technology

[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
