Plane reciprocating fruit and vegetable dryer

Abstract

The invention relates to a plane reciprocating fruit and vegetable drying machine, which comprises a hot air furnace, a heat exchanger, an air distributing device, a support frame and drying sections and is characterized in that an air outlet of the hot air furnace is connected with the heat exchanger, the heat exchanger is connected with the air distributing device, the air distributing device is connected with at least two serially connected drying sections, and the bottom surfaces of the drying sections are supported by support frames with different heights and are in step-shaped arrangement. The drying machine provided by the invention has the advantages that a plane reciprocating tunnel drying method is adopted, the mass continuous production requirements of large-scale processing factories can be met, meanwhile, the automation degree is high, and the labor is saved; in the fruit and vegetable drying process, the turning can be carried out when fruits and vegetables fall to the next drying section, the manual turning drying is simulated, and the uniform quality and uniform color intensity of the dried fruits and vegetables can be powerfully guaranteed; meanwhile, a plurality of drying sections can be connected in series to be used by users, and the requirements of different drying degrees can be met.

Description

technical field

[0001] The invention relates to a fruit and vegetable drying equipment, in particular to a plane reciprocating fruit and vegetable drying machine. Background technique

[0002] Fruits and vegetables are an important source of vitamins, minerals and dietary fiber necessary for daily life. Their tissues are tender, have high water content, are perishable and deteriorate, and are not resistant to storage. In order to facilitate eating and storage, some areas continue to use traditional drying methods such as artificial drying and oven baking to dry fruits and vegetables. Artificial drying is greatly affected by the weather, and fruits and vegetables are easy to rot and deteriorate, causing economic losses. At the same time, the drying efficiency is low. The drying process will cause secondary pollution, which cannot meet the requirements of hygienic food; the drying room is difficult to control the temperature, and the quality of the dried vegetables cannot be g...

Examples

Embodiment 1

[0037] Such as figure 1 As shown, the planar reciprocating fruit and vegetable dryer consists of a bracket 7, a heat exchanger 2, a hot air channel supervisor 3, a wind distribution box 4, a distribution pipe 5, a branch pipe 8, an air distribution flower door 18 on the branch pipe, an insert plate 6, and an air suction port. Tianyuan place 10, blower fan 9, coaming board 13, slag removal door 23, inspection door 24, movable beam cart 27, movable beam 25, fixed beam 26, movable push plate 17 reciprocating with movable beam cart 27, and It is composed of a fixed push plate 16 connected together with a fixed beam, a feed hopper 14, a rotating hand wheel 11 and a gate 15 for adjusting material thickness through a leading screw. The flue gas produced by the hot blast stove directly enters the heat exchanger, and the hot air flowing out of the heat exchanger enters the air distribution pipe network. The air distribution pipe network is connected to at least two drying sections conn...

Embodiment 2

[0045] It is basically the same as Example 1, and the same part will not be repeated. The difference is that multiple drying sections can be used in conjunction. When the fruits and vegetables pass through multiple drying sections, the moisture content of the final fruits and vegetables is lower. When there are fewer drying sections, the moisture content of the final fruits and vegetables is reduced correspondingly. Realize the drying needs of different moisture content of fruits and vegetables. Fruits and vegetables that have passed through the previous drying section no longer enter the feed hopper 14 of the next drying section. After drying to the required moisture content, the drying process is no longer carried out but directly collected through the discharge plate 20 without connecting to the next drying section. After the drying operation is finished, the residues in the ventilation chamber of the main body of the dryer can be removed through the slag removal door.
