A plum drying device with heat circulation

Abstract

This utility model relates to the field of plum drying equipment, and more particularly to a hot-circulation plum drying device, including a drying oven, a first air guide pipe, a drawer, and several second air guide pipes. The first air guide pipe, the second air guide pipes, and the U-shaped pipe are spliced ​​together to form a ventilation duct, which facilitates the circulation of hot air produced by the hot air blower. Air is blown from the top and bottom of both sides of the drawer, so that the plums inside the drawer are heated evenly from top to bottom, eliminating the need to turn them over in the middle and speeding up the drying process. The circulating fan allows the hot air to flow back and can be recycled to avoid waste. The ventilation duct is equipped with a heating pipe, which can heat the returning air and ensure that its temperature is maintained at a high level. In addition, the drying oven body is equipped with a heat insulation layer, which can accelerate the drying speed.

Description

Technical Field

[0001] This utility model relates to the field of plum drying equipment, specifically a plum drying device with heat circulation. Background Technology

[0002] Dried plums are a type of dried fruit made by sun-drying or baking fresh plums. Dried plums are a type of dried fruit, not a medicine. Consuming small or moderate amounts can supplement the body's nutritional needs and improve immunity. Drying machines are often used to speed up the production process.

[0003] However, the existing technology has the following drawbacks:

[0004] However, in existing drying equipment, hot air is lost directly from the bottom of the equipment after passing through the sealing strip without a recycling device, resulting in serious energy waste. Furthermore, the thermal efficiency is low and the heat loss is large, requiring an increase in the volume of the drying equipment or an extension of the drying time to achieve a complete drying effect, which will occupy factory space.
