The machine has large output, and can extrude rice bran, soybean, corn and big Rice noodles. Expanded rice bran can be preserved for more than two months, the production capacity of the extractor is increased by 30%, the residual oil in the dry meal is less than 1%, and the protein content and color of the bran meal are better than those of granulation, drying, and leaching. Our company's products have won the titles of "Famous and Excellent Products" and "Quality Trustworthy Products" multiple times, and have also won the gold medal at the China Science and Technology Expo. Our products are sold well throughout the country and exported to more than ten countries including Russia, Nepal, Ukraine, and South Africa.
The large-scale series oil puffing machine developed by Henan Gongliang Machinery Equipment Co., Ltd. has advanced and reasonable equipment structure, stable mechanical performance, significant process effect, long service life, and strong adaptability to oil. The principle of oil extrusion and puffing: Oil embryo sheets are subjected to mechanical effects such as extrusion, kneading, shearing, and pressure in the extrusion and puffing machine, as well as a series of physical and chemical effects such as the wet heat effect and frictional heating effect of steam injection. The cell tissue of the oil is completely destroyed, and the enzymes in the oil are passivated. When discharged from the outlet of the extrusion and puffing machine, the high-temperature and high-pressure material instantly changes from high pressure to atmospheric pressure, causing water to be quickly released from the material tissue structure, and the material is then puffed and formed, thereby obtaining loose and high-strength extrusion and puffing materials.
Characteristics of oil extrusion and puffing:
1. Improve the production capacity of the extractor
Due to the 20-30% increase in bulk density of extruded materials compared to raw materials, the processing capacity of the extractor and evaporator is increased.
2. Improve leaching speed and shorten leaching time
Due to the complete destruction of the cellular tissue of the extruded material, the porosity of the extruded material is improved, and the permeability of the solvent and mixed oil through the material layer is improved, effectively shortening the leaching time and increasing the leaching production rate.
3. The solubility of wet meal decreases, reducing the load of wet meal desolvation
Due to the good permeability and leaching properties of expanded materials, the solubility of wet meal can be reduced to about 20%, reducing the load of wet meal dissolution and solvent recovery, thus saving the steam consumption of wet meal dissolution.
4. The increase in mixed oil concentration reduces the load of mixed oil evaporation
Due to the destruction of oil cells and the improvement of permeability, the solvent ratio for leaching decreased from 0.8:1 for embryos to 0.6:1, resulting in a significant increase in the mixed oil concentration from around 20% to 28-30%. Therefore, the load on the mixed oil evaporation system and solvent recovery has been reduced. Save steam consumption in the mixed oil evaporation process.
5. Enzymes in oilseeds are passivated, improving the quality of extracted crude oil
During the extrusion and puffing process, enzymes and anti nutritional factors in the oil are passivated, avoiding the influence of lipoxygenase and phospholipase on phospholipids in the oil, reducing the content of non hydrated phospholipids in the extracted crude oil, increasing the total phospholipid content in the extracted crude oil, effectively improving the efficiency of oil refining, enhancing the quality of oil products, and improving the yield of phospholipid by-products and the quality of phospholipid products during the hydration and degumming process.
6. Increase in production capacity of rolling equipment
Puffing leaching does not require high thickness of the raw material, and the thickness of the rolled material can be appropriately relaxed, thus increasing the output of the rolling material machine.
7. Reduced energy consumption during leaching production process
Due to the increase in mixed oil concentration and the decrease in wet meal solubility, solvent loss during leaching production can be effectively reduced. Due to the increase in production capacity, the consumption of tons of materials in the production process has decreased. Reduced production costs.
8. The oil extrusion puffing machine adopts a new type of hydraulic conical plug discharge, which is easy to open and close, simple to operate, and has the effect of sliding film discharge.
