Walnut oil equipment: What are the characteristics of walnut oil processing equipment?

1. High oil yield

It adopts directional pressure bearing, multi-stage propulsion and one-time extrusion. The oil content of different raw materials will vary due to the oil content, origin, storage time, environment, etc. Generally speaking, the oil yield of pressed raw materials such as sunflower seeds, linseeds, and peanuts is above 95%.

2. Simple operation

Intelligent, fully automatic, one-button operation, no need to supervise cleaning, just pull out and insert the fixing bolts. Compact shape, small footprint.

3. Automatic filtering

It uses the principle of negative pressure, adopts vacuum diverting technology, has a built-in vacuum diverter, and cleverly designs the inclination angle and aperture of the filter to separate the oil residue and introduce the deep separation of oil into the oil cup.

4. Safety and Health

The use of 304 food-grade steel is easy to clean without residue; physical low-temperature pressing can maximize the retention of nutrients contained in peanuts, which is safe and healthy.

Common problems and solutions of walnut oil extraction

Problem: The hydraulic press stops suddenly during use.

Option 1: ① Start the machine by idling and preheating the shot blasting chamber. A large amount of oil enters the pressing chamber without pressing chamber and grinding heat;

②Thicken the pancakes. It may be that the filter cake is too thin and the pressure in the press chamber is too high; the cake was too dry during the trial run.

Option 2: The frame of the hydraulic press is damaged.

Solution 2: It may be that the shaft inside the walnut oil press is stuck, and the V-belt is forcibly reversed manually, causing the main shaft to be forcibly reversed.

Problem: The cage of the walnut oil press is damaged.

Option 3: ① When the initial pressure discharge oil is too much, reduce the oil volume appropriately;

② Metal, stones and other debris enter the pressing chamber of the oil press, and walnuts need to be pre-treated before use;

③ Excessive pressing times and insufficient water. Reduce the number of compressions or add water for appropriate compressions.

What is the price of small walnut oil press?

Walnut oil presses in walnut oil processing equipment are generally divided into large and small. The price of a small walnut oil press is around a thousand yuan, and the price of a large walnut oil press is around a few thousand yuan.
