Food processors with piston seals

Abstract

The invention relates to a food processing machine with a piston type sealing device. It mainly includes the main body of the food processor composed of a crushing device, a motor, a barrel body and a control circuit board. A piston-type sealing device is arranged in the barrel, which is slidingly fitted and sealed with the inner wall of the barrel, and can move along the longitudinal axis of the barrel in the barrel. The piston type sealing device includes a piston body with or without a sealing ring. The piston type sealing device is equipped with a locking positioning device, so that the piston type sealing device can be fixed at a certain position in the barrel. According to the volume of the actual food liquid, the present invention can push the piston-type sealing device to the position close to the liquid surface of the food in the barrel, discharge the air in the barrel and seal the barrel at the same time, and prevent the air outside the barrel from entering during the crushing process, which can reduce and avoid food Oxidation during the crushing process of the liquid by a food processor reduces nutrient loss and maintains a good taste and appearance color.

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
