Drying device for dried fruit processing production line

Abstract

The invention discloses a drying device for a dried fruit processing production line. The drying device comprises a box internally provided with a horizontal conveying belt, wherein the inner top surface of the box is provided with an electric heating plate or a heating wire; the interior, below the horizontal conveying belt, of the box is provided with a plurality of conical wind catchers side by side; one side wall of each conical wind catcher is provided with a blower; along the operating direction of the conveying belt, the inlet of the air suction pipe of the previous blower is at least arranged on the top surface of the box above the adjacent conical wind catcher; the blowpipe of each blower is horizontally arranged at the center of the bottom surface of each conical wind catcher; rectangular air holes are uniformly distributed in the semi-cylindrical pipe wall of each blowpipe at intervals and are arranged along the axis direction of the blowpipe; the width of each rectangular air hole is 3-10mm; the widths of the rectangular air holes adjacent to the left and right sides of the inner wall of each conical wind catcher are greater, and the widths of the rectangular air holes adjacent to the top surface of the conveyer belt are smaller; and semi-cylindrical ribs or semispherical bulges are uniformly distributed on the inner wall of each conical wind catcher at intervals.

Description

technical field [0001] The invention relates to a drying device of a dried fruit processing line. Background technique [0002] With the improvement of people's living standards, dried fruit has received more and more attention because of its rich nutrition and storage resistance. The post-processing and cleaning of dried fruit is an important factor in determining the quality level of dried fruit. During the drying process of dried fruit, all kinds of dirt are easy to accumulate in the surface texture. If the washing is not thorough, various dirt will remain in the surface texture of the dried fruit. However, if the washing time is too long, it will not only waste water, but also easily cause the dried fruit to absorb water. The swelling phenomenon will increase the energy consumption and processing difficulty of the subsequent drying process. Existing dried fruit dehydration and drying equipment often adopts centrifugal dehydration dryer. This high-speed rotating dehydra...

Problems solved by technology

During the drying process of dried fruit, all kinds of dirt are easy to accumulate in the surface texture. If the washing is not thorough, various dirt will remain in the surface texture of the dried fruit. However, if the washing time is too long, it will not only waste water, but also easily cause the dried fruit to absorb water. Bubble phenomenon, increase the energy consumption and processing difficulty of the subsequent drying process

Existing dried fruit dehydration and drying equipment often adopts centrifugal dehydration dryer. This high-speed rotating dehydration and drying method is likely to cause serious damage to the shape of dried fruit, and after the dried fruit is cleaned, there is no fast and low-energy drying method. Drying the dried fruit will cause the dried fruit to absorb too much water, which will affect the quality of the dried fruit
