Manufacturing method of drying screen

Abstract

The invention relates to a manufacturing method of a drying screen. The manufacturing method comprises the following steps: preparing bamboo splits, and braiding the bamboo splits into a screen mesh;cutting for preparing screen frame rods with the corresponding sizes, opening assembling holes in the screen frame rods, assembling the screen frame rods into a screen frame, and fixing the screen mesh to the bottom of the screen frame; and cutting for preparing frame rods with the corresponding sizes, opening screws holes in the frame rods, assembling the frame rods into a frame on the outer sideof the screen frame so as to enable the screen frame rods to be positioned in grooves of the frame rods, and then assembling compression springs and assembling rods on the frame and the screen frameso as to mount the screen frame on the frame in a floating manner. Through adoption of a technical scheme provided by the invention, osmund can be effectively dried, the drying efficiency and the uniformity are improved, and the existing defects are overcome.

Description

technical field [0001] The invention relates to the field of agricultural product processing equipment, in particular to a method for manufacturing a drying sieve. Background technique [0002] During the primary processing of Osmanthus welt, it is necessary to use drying equipment to dry and dehydrate it. A kind of drying equipment has been disclosed in the Chinese patent of the name "Wei Cai drying equipment" (Application No.: 2014101846544) that was first applied for. There are some flaws. For example, in this Oyster drying equipment, an insertion port is set at the bottom of the oven, and a removal port is set on the upper part, and the Oyster that is gradually dried is lifted from the bottom to the top in the oven, but the water vapor steamed from the Oyster in the oven is released from the lower part of the oven. Move upwards, so that the upper part of the welt that has been dried and has a lower moisture content will be affected by the water vapor steamed from the l...

AI Technical Summary

Problems solved by technology

For example, in this Oyster drying equipment, an insertion port is set at the bottom of the oven, and a removal port is set on the upper part, and the Oyster that is gradually dried is lifted from the bottom to the top in the oven, but the water vapor steamed from the Oyster in the oven is released from the lower part of the oven. Move upwards, so that the upper part has been dried and the lower moisture content of the welt will be affected by the steam from the lower part of the welt with high moisture content, so that the time for the upper part of the welt to reach the preset moisture content is greatly extended

Secondly, the drying sieves are stacked together in the oven, and there is no gap between the upper and lower drying sieves, so the heat of the weed is uneven, and the steamed water vapor is difficult to be removed quickly, making the weed The drying time of the

In addition, the drying efficiency of the part of the weed that is attached to the surface of the bamboo strips that constitute the screen is much lower than that of other parts, especially when the initial moisture content of the weed is high, because the surface is always in contact with the surface of the bamboo strips. During the drying process in the oven, the weed will not move, and even the surface of the weed will stick to the bamboo strips after drying, so that the moisture content of this part is higher than other places, and the finished weed will be produced in this way. Although the overall moisture content of the vegetables is controlled within the preset range, in the long-term storage process, mildew will occur due to the influence of the local high moisture content, making the whole bag of Osmunda go bad, causing serious economic losses
