What major equipment is needed to manufacture walnut oil on a large scale

Walnut oil equipment is required to extract walnut oil. The process of this equipment adopts the pure physical pressing method to extract oil, which solves the problem of raw fragrance and fragrance retention of walnut oil.

The process abolishes the solvent, alkali, ultra-high temperature refining and other unfavorable processes that affect the refined oil used in the leaching oil, so as to preserve the natural nutrients in the finished oil, maintain the original taste, mellow fragrance, no solvent residue and soap content, is a walnut oil making process that combines modern technology with traditional technology.

After the cleaning of the raw materials are graded, the graded good walnuts are directly used as food, and the broken and broken walnuts enter the oil press.

The machine-pressed crude oil is separated by the sedimentation and separation of the oil tank, filtered by the leaf filter, and the unique centrifugal degumming method of Xinxiang Hongyang Machinery is used to remove the gum, and then enters the refined oil storage tank after drying, cooling, and plate and frame filtration. The use of centrifugal degumming method shortens the natural settling time of the gum and reduces the investment in equipment and housing construction.

Walnut oil production equipment is mainly divided into two categories according to different processing technology, first, cold-pressed walnut oil production line (hydraulic oil press) second, hot-pressed walnut oil production line (spiral oil press), but at present, the main domestic use of hydraulic oil press cold press, cold pressing method (hydraulic oil press press) in less than 60 degrees Celsius production environment processing, such walnut oil nutrients will not be destroyed, more original; Therefore, here we only talk about the composition and main process of the complete set of equipment of walnut oil cold press;

First, the cold pressing process of walnut oil press.

The process is mainly divided into pressing and refining, among which the refining equipment is suitable for medium and large oil mills due to its high cost, while the walnut oil itself has good oil quality, which is not a necessary equipment for small oil mills or workshops;

Pressing section process: walnut shelling, walnut kernel, hydraulic oil press, oil extraction, filtration, walnut crude oil.

Refining section process: walnut crude oil, dephosphorization and deacidification, vacuum drying, decolorization, deodorization, finished walnut oil.

Second, the cold-pressed walnut oil is composed of complete sets of equipment.

Shell Removal Machine Cleaning Screen Hydraulic Oil Press Filter (Vacuum Filter, Plate and Frame Filter, Centrifugal Filter, etc.) Refining equipment (not required).

This requires oil extraction equipment, and then a series of processes such as refining, refining, degreasing, etc.

How much does it cost to invest in a small walnut oil processing plant? What equipment do you need to buy for walnut oil processing?

Hello. First, the construction of the plant and electricity cost walnut oil processing plant needs to meet the basic requirements of walnut processing equipment, raw material workshop, processing workshop, finished product workshop, and power load verification can be operated normally. The investment in the power of the plant is based on the local consumption level.

Second, the raw material reserve inventory cost of raw material reserves can not be over-connected, according to the equipment capacity, to ensure that the daily processing can not be over-stored, raw material investment according to the local consumption level.

Third, the equipment composition of the walnut processing plant and the best small walnut oil processing equipment 5-300,000 vertical, medium and large 30-2 million, the manufacturer recommends Henan Zhongrui grain and oil machinery, Zhongrui after-sales good.

Fourth, walnut processing plant certificate details machine cost, food production license (technical supervision bureau), business license (after-work Tanhu business bureau), tax registration certificate (local taxation bureau), health license (health bureau), grain purchase license (food bureau), employee health certificate, other documents required by the local food and drug administration according to the specific walnut oil processing plant scale, in different stages of the need for procedures are gradually increasing, the cost is also not high, basically the cost of work.

1. Pre-pressing: Lay a textile bag on the utensil, put an appropriate amount of walnut kernels, package the walnut kernels into small packets, put the wrapped walnut kernels in a special mold, and separate each material with a thin iron sheet between the celery layers to facilitate the outflow of oil between the material layers. Then the pressure is applied, and when the pressure rises to 4 megapascals, the oil begins to be produced; When the pressure rises to 10 megapascals, very little walnut oil flows out of Hungerland, and the pressure can be discharged.

2. Crushing: The structure of the pressed walnut kernel has been changed due to the action of external force, and then processed by the crusher and broken into small pieces, which is conducive to billet rolling.

3. Rolling: The rolled walnut kernel billet has a certain toughness and structure, and the powder degree is small, which is suitable for extraction conditions. During extraction, the solvent is easy to penetrate into the meal, and the residual oil of the meal is low.

4. Solvent low-temperature leaching: the solvent properties determine that the leacher is a tank group leacher, with a loading capacity of about 65% and a material-solution ratio of 1 to 1. The leaching and desolubilization of the material are carried out in the same equipment.

1. Pre-pressing First of all, lay a textile bag on the utensil, put an appropriate amount of walnut kernels, package the walnut kernels into small bags (5 kg per package is the most suitable), put the wrapped walnut kernels in a special mold (there are many holes in the mold, used to flow oil, the mold should have a suitable thickness and can withstand a certain pressure), and each material layer should be separated by a thin iron sheet to facilitate the outflow of oil between the material layers. Then the pressure is applied, and when the pressure rises to 4 megapascals, the oil begins to be produced; When the pressure rises to 10 megapascals, very little walnut oil flows out, and the pressure can be discharged. The main point is that the smaller the bag, the higher the oil yield; The pressure should be less and diligent, and the pressure should not be too high at one time, otherwise the oil is easy to be sprayed out in the form of slurry or the oil channel between the oil is closed and contracted, and the oil yield will decrease.

During the entire oil extraction process, the walnut kernels are not heated and there is no thermal denaturation. The walnut oil squeezed out is light in color and translucent, and the oil output is about 32 of the weight of the kernel. Walnut cake meal is semi-defatted, the meal is loose, has the inherent fragrance of walnut, and the protein is unchanged, which is convenient for the development and utilization of walnut protein.

2. Crushing: The structure of the pressed walnut kernel has been changed due to the action of external force, and then processed by the crusher and broken into small pieces, which is conducive to billet rolling. It is required that the powder degree is small, and the particle size meets the rolling conditions, which is convenient for the rolling mill to eat materials. 3. Billet rolling Billet rolling is a very important process, which directly affects the leaching effect.

The rolled walnut kernel billet has a certain toughness and structure, and the powder degree is small, which is suitable for extraction conditions. During extraction, the solvent is easy to penetrate into the meal, and the residual oil of the meal is low. 4. Solvent low-temperature leaching The nature of the solvent determines that the leacher is a tank group leacher, with a loading capacity of about 65 and a material-solution ratio of 1:

1。The leaching and desolubilization of the material are carried out in the same equipment. The obtained walnut oil is light yellow, and the oil residue is less than 50 milligrams kilograms, the meal is white, the meal residual oil is less than 3, and the meal residue is less than 400 milligrams kilograms.

The active substances (vitamins, bioactive enzymes, etc.) in crude oil and meal are basically not destroyed.

The simpler is hydraulic pressing, using walnut kernels.

There are four types of walnut oil making process, the first type is the traditional mechanical pressing process; The second type is the use of pre-pressing-leaching process; The third type is the aqueous extraction process; The fourth type is the supercritical CO2 extraction process. In addition, there are also studies on the process of microwave extraction of walnut oil and the preparation process of walnut oil microcapsulation technology. At the same time, walnut is a small special oil, and the appropriate preparation method must be selected according to its characteristics, so as to ensure the natural quality of walnut oil while avoiding the denaturation of walnut protein.

The first two are commonly used production processes in production, which can meet the above requirements, and the operation process is simple, high efficiency, and suitable for industrial production.
