Food processor with piston type sealing device

Abstract

The invention relates to a food processor with a piston type sealing device. The food processor comprises a main food processor body consisting of a smashing device, a motor, a barrel body, a control circuit board and the like. A piston type sealing device is arranged in the barrel body, is in sliding fit or sliding seal with the inner wall of the barrel body, and can move along the longitudinal axis in the barrel body. The piston type sealing device comprises a main piston body which is provided with or not provided with a sealing ring, and is provided with a locking-positioning device, so as to be fixed in one position in the barrel body. In the food processor of the invention, according to the volume of the practical foodstuff liquid, the piston type sealing device is pushed to a position close to the foodstuff liquid level in the barrel body, air in the barrel body is discharged, simultaneously, the barrel body is sealed, air outside the barrel body is prevented from entering in the smashing process, the possibility of oxidization of foodstuff liquid processed by the food processor in the smashing process can be reduced and avoided, the nutrition loss is reduced, and the good mouthfeel and appearance color are kept.

Description

technical field [0001] The invention relates to a food processing machine with a piston type sealing device. Background technique [0002] Food processors include volumetric food processors and non-volume food processors capable of pulverizing food materials. Volumetric food processors include soybean milk machines, rice paste machines, fruit and vegetable juice machines, food processors, mixers and other volumetric food processors for crushing food materials. Non-volumetric food processors include hand mixers, stand mixers, and stand mixers. The common feature of volumetric food processors is that there is a barrel for holding food and a crushing tool device. It is divided into two types: those with heating devices (such as soybean milk machines, rice flour machines, etc.) and those without heating devices. The non-volume food processor itself does not have a barrel for food, it only has an electric crushing tool device, which needs to be inserted into other containers co...

AI Technical Summary

Problems solved by technology

[0009] Currently commercially available volumetric food processors have a lid on the upper part of the barrel (the head of the motor on the top itself serves as the lid of the barrel), and its existing problems are: 1. The lid is not sealed; Most of the time it is not necessary to make a full bucket of food liquid such as juice (at the same time, because the lid is not sealed, if it is completely filled, the food will overflow when crushed and stirred), which not only makes the bucket have a lot of air and the air communicated with the outside atmosphere
