A household two-stage pressing low-temperature oil press machine

Abstract

The invention relates to a household two-level pressing low temperature oil press. The oil press comprises an oil press base, a pressing mechanism and a driving mechanism, the pressing mechanism is installed on the oil press base, the driving mechanism is used for providing motive power for the pressing mechanism, the pressing mechanism includes a barrel, a pressing head, a pressing shaft and a pressing head casing, the barrel is provided with a feed port and an oil outlet, one end of the barrel is connected with the oil press base, the pressing head casing is connected with the other end of the barrel, one end of the pressing shaft is provided with screw threads and sleeved in a chamber formed by the barrel and the pressing head casing, the other end of the pressing shaft extends out of the barrel to serve as a rotating bar to be connected with the driving mechanism, the pressing head is installed in the pressing head casing, pressing space is formed by one side of the pressing head and one corresponding end of the pressing shaft, one or a plurality of material passing holes is / are arranged on the pressing head, one side surface of the pressing head where the pressing head is in a cut grafting with the pressing shaft is provided with a groove, one or a plurality of oil guide grooves which is / are communicated with the material passing holes is / are mounted on the wall surface of the groove, a heater is arranged on the pressing head casing or the barrel, and the driving mechanism and the heater are connected with a power supply. The driving mechanism includes a motor and a speed reducer which are disposed on the oil press base, and the speed reducer is in a transmission connection with a rotating shaft of the motor and the rotating bar of the pressing shaft. By means of the household two-level pressing low temperature oil press, the low temperature cold pressing can be achieved, the oil yield is high, the produced oil quality is good, and the oil press is easy to clean.

Description

technical field [0001] The invention relates to an oil press, in particular to a household secondary pressing low-temperature oil press. Background technique [0002] Edible oil is an indispensable condiment in life. With the improvement of people's quality of life, the health and hygiene requirements of edible oil are also getting higher and higher. The frequent incidents of edible oil quality in China have aroused people's doubts about the quality of commercial edible oil whose production process is not disclosed and the production raw materials are uncertain. Therefore, there is a demand for household self-extracted oil in the market. The emergence of household oil presses that can realize the whole process of oil extraction can be controlled by consumers themselves, and the types of oil plants can be selected by themselves, meets the above needs. [0003] Due to the limitation of cost and volume, the existing household oil presses cannot be equipped with high-pressure c...

AI Technical Summary

Problems solved by technology

High-temperature oil extraction can easily make oil rancid, oxidize, or convert unsaturated fatty acids into saturated fatty acids. The above reactions will produce acids, aldehydes, ketones, unsaturated fatty acids and other oxidized substances, which not only affect the sensory, taste, shorten the shelf life of edible oil, and even endanger human health
