Rapid food drying machine

Abstract

The invention discloses a food rapid drying machine. The drying machine comprises a base, a transmission box is fixedly installed on one side of the top end of the base, a tank body is fixedly installed at the top end of the transmission box, a drying barrel is rotatably installed in an inner cavity of the tank body, the barrel wall of the drying barrel is of a porous structure, a transmission mechanism used for driving the drying barrel to rotate is arranged in an inner cavity of the transmission box, the bottom of the outer wall of the tank body is fixedly connected to an air injection device for blowing in hot air, the air inlet end of the air injection device is fixedly connected to a heating device for providing hot air, and the top of the outer wall of the tank body is fixedly connected with an air extractor for extracting moisture. The hot air is blown into the tank body through the air injection device to dry food in the drying barrel, the drying barrel can rotate under the action of the transmission mechanism, so that the hot air can uniformly cover the food, moisture in the food is evaporated through the hot air, and water vapor gradually rises upwards, and is extracted through the air extractor finally, so that the water vapor is prevented from being attached to the food surface to affect the food drying speed.

Description

technical field [0001] The invention relates to the technical field of food processing equipment, in particular to a fast food drying machine.

The technical problem to be solved by the invention is to provide a drying equipment for making preserved fruit for food processing with low production cost, simple operation, uniform and comprehensive drying, and high work efficiency. ...

AI Technical Summary

Problems solved by technology

[0004] However, after the equipment dries the food with hot air, the water vapor generated during the drying of the food cannot be discharged in time. The water vapor is easy to adhere to the surface of the food, causing the food to regain moisture and the drying is not complete. Moreover, the equipment needs to introduce air from the outside for heating. Bacteria present in the outside air may attach to food surfaces and cause food contamination
