Description

Electric drive closed vacuum squeezer

Technical field

The invention belongs to foodstuff squeezings to produce juice technical field, especially a kind of electric drive closed vacuum squeezer.

Background technique

Fruit includes common apple, orange, pears etc., and vegetables include celery, cucumber etc., these fruits and vegetables are in people Daily life in be the food materials being often eaten, with the improvement of living standards, people are increasingly not content with fruit and vegetable Traditional eating method of dish, it is desirable to be able to more fully, directly obtain the nutritional ingredient in foodstuff, thus each producer develops Fruits and vegetables, can be squeezed out juice by various press apparatus out, and people's these juice capable of direct drinking greatly facilitate People's lives.Above-mentioned press apparatus includes the structures such as push type, press handle type, and push type is in cylinder upper end installation one with net The fruit of the succulence such as orange, orange is directly born against in protrusion or is pressed in protrusion again in upper cover by the protrusion in hole, firmly to Lower pressure flows into juice in cylinder by mesh；Press handle type is that fixed handle is installed on cylinder, cuts with scissors dress pressure in cylinder side The upper cover that, handle bottom surface installation one is agreed with cylinder upper end, the installation of cylinder upper end is with meshed protrusion, by fruit when use It is placed in protrusion, firmly depresses handle, upper cover and protrusion is made to squeeze out juice.In above two structure, if using electricity Dynamic driving method realizes squeezing movement, and expressing process can be very fast and squeezing thorough, meanwhile, electronic driving is added After mode, squeeze force is larger, it can be made to be used for the oil expression of the foodstuffs such as peanut, soybean.

In addition to this, people also develop the spiral isostructural press apparatus of other types, but all these equipment Expressing process be all to carry out in air, about 21% oxygen is contained in air, contains phenolic substances in plant tissue, works as squeezing After cell tissue is destroyed in the process, oxygen just a large amount of intrusions, phenolase phenol substance catalytic forms quinone and its polymer generates enzymatic Browning reaction, enzymatic browning are oxidized the foodstuff juice (fruit juice, vegetable juice, edible oil etc.) squeezed out, cause loss big Nutrition is measured, and color and mouthfeel are all deteriorated.

Summary of the invention

It is an object of the invention to overcome the deficiencies of the prior art and provide completing to squeeze in the way of electrically driven (operated), squeeze With connect that juice keeps vacuum state and a kind of electric drive for avoiding the juice squeezed out in expressing process from being oxidized by oxygen is closed Vacuum presser.
