Can an advanced rapeseed oil press really improve the oil yield of rapeseed?

The price of hydraulic press is determined by many factors of equipment. The prices of different types, different models, different output and different materials are different. According to its function, oil press can be divided into screw oil press and hydraulic oil press.

1, hydraulic oil press

Hydraulic oil press is a traditional small oil press, and the production process is intermittent. This process is characterized by low technical requirements, high oil yield and good crude oil quality, but it is labor intensive. Hydraulic oil press is suitable for small capacity and small workshop production, with a daily production capacity of 65,438+0 tons.

2. Screw oil press

Automatic screw oil press is a kind of oil press that can work continuously. The technical features are: low technical requirements for operation, high oil yield, poor quality of crude oil and lower labor intensity than hydraulic oil press. Fully automatic screw oil press is suitable for small processing capacity and small workshop production, and the daily processing capacity of each machine is 2-8 tons.

3. Large and medium-sized screw oil press

Screw oil press unit is suitable for large and medium-sized, continuous and large-capacity oil plants. The technical features are: continuous production, low labor intensity and high oil yield.

A, rapeseed oil press equipment production process:

1. Cold pressing process: rapeseed → cleaning and impurity removal → cold pressing → cold pressed crude oil → coarse filtration → refining → cold pressed oil → rapeseed cake.

2. Hot pressing process: rapeseed → cleaning and impurity removal → steaming and frying → oil pressing → precipitation → refining → tea oil; Main equipment components: hoist, cleaning screen, steamer, oil press, filter, crude oil temporary storage box.

Second, rapeseed oil crude oil refining equipment production process

Crude oil-alkali refining-degumming-decoloring-deodorization-dewaxing workshop (or refined oil workshop)

Main equipment: refining tank, decoloring tank, deodorizing tank, heat conduction oil furnace, filter, etc.

III. Process flow of rapeseed oil dewaxing equipment

When processing oil and fat, the wax inherent in oil and fat can be separated from oil and fat through winterization and dewaxing, thus improving the nutritional value of oil and fat and improving the taste and quality of oil and fat.

Main equipment composition: freezer, filter, crystallization tank, refining oil tank, etc.

The cost of equipment is related to the production capacity, configuration and the required quality of refined oil, which cannot be summarized in a word;
