Flow equalizing apparatus used in heated air circulation sterilization dryer for heating cavity

Abstract

The present invention disclose a flow equalizing apparatus used in heated air circulation sterilization dryer for heating cavity, including flow equalizing board, flow controlling board and diffuser cover arranged between the air heater and the dryer filter, the flow board is mounted beneath the filter, the flow controlling board is mounted beneath working objects. The diffuser cover includes diffuser frame, fan housing connected with the air heater air outlet and flow diffuser plate mounted onto the filter air inlet, the air outlet of the fan housing is connected with inlet frame of the flowdiffuser frame, the air outlet of diffuser frame is connected with flow diffuwer plate. The diffuser frame is composed of a plurality of criss-cross splitter plates, and forming a plurality of air inlet holes on the air inlet end surface on the diffuser frame via criss-cross splitter plates, and forming a plurality of air outlet holes on the air outlet end surface of the diffuser frame. The invention is a flow equalizing apparatus for heated air circulation sterilization dryer heating cavity with simple and compact structure, low cost, convenient installation, wide application range, being capable of improving the work efficiency of machine.

Description

technical field [0001] The invention mainly relates to the field of hot air circulation type sterilization dryer, in particular to a flow equalizing device used in the heating cavity of the hot air circulation type sterilization dryer. Background technique [0002] In the food, pharmaceutical and other packaging machinery industries, heat uniformity is an important indicator for the verification of hot air circulation sterilization dryers (heat uniformity refers to the temperature difference between the highest temperature and the lowest temperature on the same cross-section of the oven), The heating principle is to exchange heat between the heater and the circulating air, and the circulating air is heated by the hot air blower to the wind cover, enters the high-temperature high-efficiency filter, and then exchanges heat with the medicine bottle or food, so the hot air entering the cavity The uniformity of the air volume directly affects the heating effect of the medicine bo...

AI Technical Summary

Problems solved by technology

Due to the limitation of the circulating air structure, the heating section of the hot air circulation sterilization dryer is divided into two structures: single-side heater and double-side heater. The wider the box, the more difficult it is to control the air volume in the cavity of the box. Installed in the return air channel, it is easy to appear that the closer to the return air channel, the faster the wind speed, the greater the air volume, the faster the heating, and the farther away from the return air channel, the slower the wind speed, the smaller the air volume, and the slower the heating, resulting in farther away from the return air channel. It is difficult to heat the medicine bottle or food in the channel, and the objects on the same cross section are heated unevenly
