Drum type food dryer with thermal cycles

Abstract

The invention discloses a drum-type food dryer with heat cycle, which comprises a drum rotating device, a heating device, a hot air blower, a casing, a box door, universal wheels, a through-hole hot air dispersion plate and a heat cycle system; The inside of the shell is provided with a drum rotating device, a heating device and a hot air blower; the thermal cycle system is provided with a shell, an air outlet pipe, a hot air blower, an activated carbon drying device, a spherical drying device, an air inlet pipe and a hot air gathering cavity; the device of the present invention Through the setting of the drum with through holes in the drum rotating device and the rotating device, the rotation of the drum with through holes can make the food evenly heated; through the setting of the screw auger inside the drum with through holes, the food after drying is realized. It flows out automatically, and at the same time drives the rotation of food during the drying process; through the setting of the heat circulation system, it has the function of recycling resources; through the setting of the spherical drying device and the activated carbon drying device, it has the function of absorbing moisture in the hot air.

Description

technical field [0001] The invention relates to the technical field of food processing equipment, in particular to a drum-type food dryer with a heat cycle. Background technique [0002] Drying is the most widely used food preservation method. Many foods need to be kept dry during the preservation process. After drying, the water activity of the food is reduced, which is conducive to long-term storage at room temperature. At the same time, the weight of the dried food is reduced. The reduced volume can significantly save the cost of packaging, storage, and transportation; drying is not only beneficial to food preservation, but also suitable drying and dehydration of soybeans, peanuts, corn, etc., is also conducive to post-processing and improve product quality; now people usually dry food They are all realized by air-drying and sun-drying. Although the cost of this drying method is low, the drying time is long, which greatly affects the production efficiency; and natural dry...

[0002] Drying is the most widely used food preservation method. Many foods need to be kept dry during the preservation process. After drying, the water activity of the food is reduced, which is conducive to long-term storage at room temperature. At the same time, the weight of the dried food is reduced. The reduced volume can significantly save the cost of packaging, storage, and transportation; drying is not only beneficial to food preservation, but also suitable drying and dehydration of soybeans, peanuts, corn, etc., is also conducive to post-processing and improve product quality; now people usually dry food They are all realized by air-drying and sun-drying. Although the cost of this drying method is low, the drying time is long, which greatly affects the production efficiency; and natural drying requires a large drying area, which is affected by climate conditions. The impact is very large, so it is very inconvenient in the actual operation process
