Vegetable dehydrator adopting stiffener chain plates

Abstract

The invention provides a vegetable dehydrator adopting stiffener chain plates. The vegetable dehydrator is characterized in that the interior of a box body is horizontally divided into multiple layers by spacer plates; a group of transporters driven by a transmission device step by step to run are arranged in each layer; the stiffener chain plates are divided into two kinds, namely stiffener chain plates with a plurality of air vents on panels and stiffener chain plates without holes; one long side of each panel is along the bus of a stiffener; the two planes of the panel are maintained to be symmetrical relative to the stiffener and are fixedly connected with the stiffener; each stiffener chain plate is supported on a guide rail to form a groove-shaped material channel; a material guide groove is arranged below the tail end of each channel; an infrared radiation device is arranged above a channel in the box body at each layer with a larger layer number; a draught hole is arranged on the upper part of the side wall at one end of the box body at each layer and is connected with a fan by a draught pipe; air inlets are arranged at the two ends of the side wall of the box body at each layer with a smaller layer number and are connected with an air heater by an air supply pipe; a feeding hole is arranged at the top of the box body; and a discharge hole is arranged at the bottom of the box body. The vegetable dehydrator has the advantages of stable working performances, high reliability and good vegetable drying quality.

Description

technical field [0001] The invention provides a vegetable dehydrator with reinforced rods and chain plates, specifically a device for dehydrating and drying vegetables by utilizing two heat sources of infrared radiation and hot air. Background technique [0002] At present, the commonly used vegetable dehydration and drying method in China is simple hot air drying. In order to ensure the drying speed, the temperature of the hot air is generally relatively high, and in addition, the drying is carried out under normal pressure. Due to oxidation, it is easy to cause a large loss of nutrients such as organic matter and Vc in the vegetables, and the color of the dried vegetables will deteriorate. The loss of nutrients is serious. , the grade is lowered. Therefore, the dried vegetables obtained by drying in a simple hot air convection mode can no longer meet people's quality requirements for dehydrated vegetables, and its market competitiveness is also getting worse.

Problems solved by technology

However, through further tests, it was found that the chain plates used in the vegetable dehydrator involved in the above-mentioned patents are all single-layer, poor in rigidity, and easily deformed.

Each chain plate is hung on the pin shafts protruding inward of the two conveyor chains through the hanging holes at both ends. Therefore, when the chain plate is bent and deformed, the chain plate will fall off from the conveyor chain due to the shortened length.
