Title:
ELECTRIC-POWERED VACUUM PRESSING MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/133482
Kind Code:
A1
Abstract:
An electric-powered vacuum pressing machine, comprising a pressing cylinder (9), a juice receiving part, a piston (10), an electric-powered telescoping mechanism, an electric vacuuming pump (17), and a machine body (7). The sliding piston (10) is mounted in the pressing cylinder (9). The outer edge of the piston (10) tightly fits the inner edge of the pressing cylinder (9). The piston (10) divides the pressing cylinder (9) into a travel cavity (2) and a pressing cavity (13) separated from each other. The top surface of the piston (10) is arranged within the travel cavity (2). The bottom surface of the piston (10) is arranged within the pressing cavity (13). Kept in a vacuumed environment are food such as fruits or vegetables whilst being pressed and the juice (comprising oil) when entering the juice receiving part or a juice receiving tanks, thus preventing the problem in the prior art of discoloration and deterioration of the juice due to oxygenation. Compared with a vacuum spiral juice pressing machine, cleaning is easy (each time after use, washing is required for only three components, namely the juice receiving part, the pressing cylinder (9), and the piston (10), while the vacuum spiral juice pressing machine requires the washing of seven components, namely a sealing cover, a feeder cylinder, a spiral shaft, a cylindrical filter, a juicing cavity, a juice receiving cup, and a pulp cup) and operation is easy (only the three components need to be mounted at minimum, while the vacuum spiral juice pressing machine requires at least the 7 components to be mounted).
