Flashboard type vacuum sealing device

Abstract

The invention discloses a flashboard type vacuum sealing device and relates to the sealing device capable of keeping vacuum degree under the condition that bulk material and packaging material are continuously fed and discharged, The flashboard type vacuum sealing device is composed of two groups of sealing valve banks, a forevacuum cabin, a vacuum return-flow system and a pressure gas supply system which can be combined into three different processing manners, that is, feeding and discharging manner of bulk material vertical flashboard type vacuum sealing device, feeding and discharging manner of bulk material or packaging straight-line falling flat-pushing flashboard type vacuum sealing device and feeding and discharging manner of packaging right-angle flat-pushing flashboard type vacuum sealing device; the flashboard type vacuum sealing device uses a feeding-discharging sealing device under the continuous vacuum or pressure condition, or some equipment adopts a group of sealing valve bank as a sealing valve for sealing in interstitial pressure or vacuum processing; and the feeding-discharging sealing device and the sealing valve bank are suitable for the supporting facility of a continuous feeding-discharging sealing device of a continuous vacuum dryer, a continuous vacuum fryer, a continuous vacuum precooling machine, a continuous vacuum impregnating machine and the like.

Description

technical field [0001] The invention relates to a vacuum sealing device, in particular to a gate-type vacuum sealing device, which is suitable for a sealing device that can maintain a vacuum degree when materials can be continuously fed in and out, and belongs to the continuous flow of mechanical equipment such as food, Chinese medicinal materials, and chemical industry. Vacuum or pressure processing equipment such as drying, frying, quenching, dipping, pre-cooling, high temperature and high pressure sterilization and other equipment. Background technique [0002] Continuous vacuum drying, continuous vacuum frying, continuous vacuum impregnation, continuous vacuum quenching, continuous vacuum freeze-drying, continuous vacuum precooling are required in the case of a certain vacuum degree in the processing of food, Chinese medicinal materials, chemical and other products. And the processing of high temperature and high pressure sterilization, etc., and it is necessary to maint...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that the sealing plate of the ram-type vacuum sealing device cannot be opened and it is necessary to prevent debris from being easily generated after vacuum frying, the U-shaped sealing ring is easy to explode, and the sealing plate is easy to cause debris to stick to the sealing ring to make the seal Unreliable, reducing the resistance of the sealing plate to and fro
