电驱动封闭式真空压榨机Electric drive closed vacuum press

技术领域Technical field

本发明属于食料压榨制取汁液技术领域，尤其是一种电驱动封闭式真空压榨机。The invention belongs to the technical field of juice extraction and juice extraction, in particular to an electric drive closed vacuum press.

背景技术Background technique

水果包括常见的苹果、橙子、梨等，蔬菜包括芹菜、黄瓜等，这些水果和蔬菜在人们的日常生活中是经常被食用的食材，随着生活水平的提高，人们越来越不满足于水果和蔬菜的传统的食用方法，希望能够更全面的、直接的获取食料中的营养成分，由此各厂家研制出各种压榨设备，其可将水果和蔬菜压榨出汁液，人们可直接饮用这些汁液，极大地方便了人们的生活。上述压榨设备包括按压式、压把式等结构，按压式是在筒体上端安装一带有网孔的凸起，将橘子、橙子等多汁的水果直接压在凸起上或嵌在上盖内再压在凸起上，用力向下压下，使汁液通过网孔流入筒体内；压把式是在筒体上安装固定把，在筒体一侧铰装压把，压把底面安装一与筒体上端契合的上盖，筒体上端安装带有网孔的凸起，使用时将水果放置在凸起上，用力压下压把，使上盖和凸起挤压出汁液。在上述两种结构中，如果采用电动的驱动方式实现压榨动作，其压榨过程会非常迅速且压榨的彻底，同时，加入电动的驱动方式后，压榨力较大，可以使其用于花生、大豆等食料的榨油。Fruits include common apples, oranges, pears, etc. Vegetables include celery, cucumbers, etc. These fruits and vegetables are often eaten in people's daily lives. With the improvement of living standards, people are increasingly dissatisfied with fruits. The traditional method of eating vegetables and vegetables hopes to obtain more comprehensive and direct access to the nutrients in the foodstuffs. As a result, various manufacturers have developed various pressing equipment, which can squeeze fruits and vegetables out of juice, and people can directly drink these juices. Greatly convenient for people's lives. The pressing device comprises a pressing type, a pressing type and the like. The pressing type is to install a protrusion with a mesh on the upper end of the barrel, and the juicy fruit such as orange and orange is directly pressed on the protrusion or embedded in the upper cover. Pressing on the protrusion again, pressing down forcefully, so that the juice flows into the cylinder through the mesh; the pressing type is to install a fixing handle on the cylinder body, and the pressing handle is hinged on the side of the cylinder body, and the bottom surface of the pressing handle is installed and The upper cover of the upper end of the cylinder is fitted with a protrusion with a mesh hole. When used, the fruit is placed on the protrusion, and the pressing handle is pressed hard to squeeze the upper cover and the protrusion to squeeze out the juice. In the above two structures, if the pressing action is realized by the electric driving method, the pressing process will be very rapid and the pressing is thorough. At the same time, after the electric driving method is added, the pressing force is large, and it can be used for peanuts and soybeans. The oil of the foodstuffs.

除此之外，人们还研制出其它种类的螺旋式等结构的压榨设备，但所有这些设备的压榨过程都是在空气中进行，空气中含有约21％氧气，植物组织中含有酚类物质，当压榨过程中细胞组织被破坏后，氧就大量侵入，酚酶催化酚类物质形成醌及其聚合物产生酶促褐变反应，酶促褐变使压榨出的食料汁液(果汁、蔬菜汁、食用油等)均被氧化，导致损失大量营养，而且颜色及口感都变差。In addition, other types of screw-type press equipment have been developed, but all of these equipment are pressed in the air, containing about 21% oxygen in the air, and phenolic substances in plant tissues. When the cell tissue is destroyed during the pressing process, oxygen invades a lot. The phenolase catalyzes the formation of phenolic substances and its polymer to produce an enzymatic browning reaction. The enzymatic browning causes the pressed food juice (juice, vegetable juice, Edible oils, etc. are all oxidized, resulting in loss of a large amount of nutrients, and the color and taste are deteriorated.
