an oven

Abstract

The invention discloses a drying box which comprises a box body, wherein a ventilating pipe is arranged on a side wall of the box body, and a fan is arranged in the ventilating pipe; an air inlet and an air outlet are formed in the ventilating pipe; the air inlet and the air outlet are respectively formed in two opposite sides of the box body; a rotating rack is arranged in the box body and comprises upper supporting rods, lower supporting rods, and a middle base rack connected with the upper supporting rods and the lower supporting rods; each upper supporting rod and the lower supporting rod which is correspondingly arranged below the upper supporting rod form a product supporting surface; each product supporting surface is used for suspending to-be-dried products and is parallel to the air convection direction inside the box body; a driving mechanism is arranged outside the box body; the driving mechanism is connected to the center of the base rack of the rotating rack in a penetrated mode and is used for driving the rotating rack to rotate; and when the rotating rack rotates, the product supporting surface is always parallel to the air convection direction inside the box body, and a heater is arranged in the box body. According to the drying box, multilayer heating of large-size flaky products can be realized, and each layer can be uniformly heated.

Description

technical field [0001] The present invention relates to a drying and heating device, and more specifically relates to an oven. Background technique [0002] The oven is a drying and heating device, which can be widely used in electromechanical, chemical, plastic and other industries, and can also be used in scientific research units to bake, dry, cure, and sterilize various products and samples. The main principle of the oven is to use the heating of the electric heater to achieve the drying of the product. In actual operation, the product to be dried is placed in the box, and then heated by a heater to dry and evaporate the moisture in the product. In actual operation, when drying some multi-layer sheet products, it is often necessary to place a material rack in the oven, and then place the products layer by layer and horizontally overlapped on the material rack for drying. However, due to the current Due to the limitations of oven structure design, the temperature of dif...

Problems solved by technology

In actual operation, when drying some multi-layer sheet products, it is often necessary to place a material rack in the oven, and then place the products layer by layer and horizontally overlapped on the material rack for drying. However, due to the current Due to the limitations of oven structure design, the temperature of different areas of the oven body is often slightly different, so when the size of the product to be dried is large, the temperature of different areas of the product is often different, and due to the comparison of air flow between each layer of products Small, so that the temperature of each part of each layer of the product cannot be evenly controlled, so that the generated water vapor cannot be removed in time, which greatly affects the baking effect; especially for some products that are sensitive to temperature, such as cloth, When the temperature is too high, it is easy to cause the product to be scorched or damaged. When the temperature is too low, the product cannot be dried for a long time. In severe cases, the fluid on the product will accumulate and affect the performance of the product. Therefore, uneven heating will seriously hinder its normal drying procedure
