How is biodiesel made

Catalytic synthesis method

Currently, most biodiesel is made by chemical method. Animal and vegetable oils have transesterification reaction with low carbon alcohol such as methanol or ethanol under high temperature and acid and alkaline catalysts. It is produced by common oil production equipment, with 10% glycerin as by-products.

Biological enzyme method

Biological enzyme method is to use lipase to induce transesterification reaction between animal fats and low carbon alcohol, and produce fatty acid methyl ester and ethyl ester. The new technique can transform animal and vegetable oil into biodiesel at room temperature, and the productive rate can be more than 90%.

Engineered microalgae method

Engineered microalgae method is to transform the physiological structure with genetic engineering technology to increase their productivity and oil content. National renewable energy laboratory (NREI) can increase the lipid content by 60%. The lipid is extracted with normal hexane.

Pellet Mill Roller

Rollers are the most important and vital components for making pellets. The main purpose of rollers is to help the material mixture to get into the die hole. Thus the roll shape and construction are designed for preventing the slippage of the material and give a smooth surface for a better discharge. The material of roller parts must be anti-bearable and not easy to be broken. The roller in our flat die pellet mill is made from precise material of alloy metal, which makes this core part wear-resistant and not easy to break. In addition, our flat die pellet mills usually have two or three rollers that enlarge the capacity of making pellets.

How to choose second-hand fruit processor machine?

The fruit processor machine industry came into being with the popularity of many fruit juices and the rise of fruit juice enterprises. Many small entrepreneurs have identified the broad development prospects of the fruit processor industry, thus investing in fruit juice production. In order to ensure the quality of second-hand fruit processor machine, we should pay attention to the following items when purchasing.

1. Before signing the contract, equipment research and consultation should be well done.
2. Check the performance of the equipment. Mechanical moving parts such as pulley, chain, gear and flywheel, and mechanical safety protection devices. Common terminal, transformer and electric cabinet. Safety warning signs for dangerous parts such as injuries, burns, burns, corrosion and electric shock. Operating instructions, technical parameters and safety precautions. Functional operation buttons, emergency stop devices, etc.
3. If the second-hand equipment is found to be unqualified, it shall promptly notify the local inspection and quarantine institution to conduct investigation and handling.
