Food drying system

Abstract

A food drying system comprises multiple drying box channels, a steam system, a front box channel door, a rear box channel door, a control plate and multiple trolleys. Each drying box channel comprises an exhaust system and two circulating systems, wherein the exhaust system is arranged between the two circulating systems. Each exhaust system comprises a fresh air heat exchanger, an exhaust fan, an air valve and an exhaust pipeline, wherein the air valve and the exhaust fan are sequentially arranged between fresh air heat exchanger and the exhaust pipeline. Each circulating system comprises a circulating fan, a manual air valve and a heat exchanger, wherein the manual air valve is arranged between the circulating fan and the heat exchanger. The steam system comprises a steam pressure reducing valve, a steam header, pipelines, a steam coil pipe, a steam trap and a control valve set, wherein the control valve set is connected with the control plate, the pipelines are connected with the heat exchangers in the circulating systems, and the steam system is arranged in a device chamber. The food drying system is suitable for drying a large number of products needing to be dried, is high in drying speed and can achieve intelligent automatic control.

Description

technical field [0001] The invention relates to a drying system, in particular to a food drying system applied in the fields of meat products and vegetables. Background technique [0002] The existing food drying system generally adopts heating sources such as electric heating tubes or electric heating wires in the drying furnace to heat the drying indoor environment. It is easy to cause the ambient temperature in the furnace to be unbalanced, which will affect the drying effect of the same batch of food, and the drying effect will also be reduced due to the accumulation of water vapor emitted from the food in the furnace during drying; In the process of food drying and processing, due to the large demand for drying products, long drying time, slow drying speed and low degree of automation, the problem of needing large-scale drying equipment is more prominent, and automatic control has become particularly necessary. Contents of the invention [0003] In order to solve the...
