Description
Technical field
The invention belongs to foodstuff squeezing and produce juice technical field, especially a kind of electric drive closed vacuum squeezer.
Background technology
Fruit includes common Fructus Mali pumilae, Fructus Citri junoris, pears etc., and vegetable includes Herba Apii graveolentis, Fructus Cucumidis sativi etc., and these fruits and vegetables are in the day of people
Being often the food materials being often eaten in life, along with growth in the living standard, people are increasingly not content with the biography of fruits and vegetables
The eating method of system, it is desirable to be able to more fully, directly obtaining the nutritional labeling in foodstuff, the most each producer develops various
Press apparatus, fruits and vegetables can be squeezed out juice, people's these juice capable of direct drinking, be very easy to people's by it
Life.Above-mentioned press apparatus includes the structure such as pressing type, press handle type, and pressing type is meshed convex at cylinder upper end installation one band
Rise, be pressed in again in projection in the fruit of the succulence such as Fructus Citri tangerinae, Fructus Citri junoris being directly born against in projection or being embedded in upper cover, firmly press downwards,
Make juice pass through mesh to flow in cylinder;Press handle type is to install fixing handle on cylinder, at cylinder side hinge dress pressure handle, at the bottom of pressure handle
A upper cover agreed with cylinder upper end is installed in face, and cylinder upper end is installed and carried meshed projection, during use, fruit is placed on projection
On, firmly depress pressure handle, make upper cover and projection squeeze out juice.In above two structure, if using electronic driving side
Formula realizes squeezing action, its expressing process can very fast and squeezing thorough, meanwhile, after adding electronic type of drive, pressure
Squeezing power is relatively big, and it can be made for the oil expression of the foodstuff such as Semen arachidis hypogaeae, Semen sojae atricolor.
In addition, people also develop the spiral isostructural press apparatus of other kind, but the squeezing of all these equipment
Journey is all to carry out in atmosphere, containing about 21% oxygen in air, containing aldehydes matter in plant tissue, when cell in expressing process
After tissue is destroyed, oxygen is the most a large amount of to be invaded, and phenolase phenol substance catalytic forms quinone and polymer produces enzymatic browning reaction, enzyme
Promoting brown stain makes the foodstuff juice (fruit juice, vegetable juice, edible oil etc.) squeezed out the most oxidized, causes large losses nutrition, and
And color and mouthfeel are all deteriorated.
