Principle Innovation

I. Biomass conversion barrier

* Conversion object: Organic cell body
* Barrier No.1: Three Layer Wrap for cell.
* Barrier No.2: crystal structure
* Other Barrier: cell wall, epidermis, waxy layer, etc

II. Pretreatment Mechanism

* Break the wall
* Three element separation
* Break down the structure
* Reduce crystallinity
* Increase porosity
* Improve accessibility

Core Technology

III. Supersonic instantaneous ejection steam explosion technology* Instantaneous ejection steam explosion (ICSE) technology is derived from the aircraft carrier aircraft accelerated take-off device
The burst speed reaches 0.00875 seconds
* The instantaneous blasting power reaches an astonishing 22MW, while foreign thermal spray tank technology is only 0.026MW;
* Ultimately, it is possible to instantly break the microstructure of biomass with low energy consumption, allowing it to be rapidly degraded;
* From principle innovation to equipment research and development, all are independent innovations, with independent and complete intellectual property rights.

Essential changes in biomass

VI. Sedimentation characteristics* All ICSE sinks to achieve complete miscibility with water.
* The thermal blast from Europe has sedimentation ratio is 0.592: 1.
* The alkali pile retting settlement ratio is 0.32: 1
* raw material alone sedimentation ratio 0.127：1

V. Hydrophilic/Hydrophobic Characteristic Index* ICSE is the only one among the four samples with a hydrophilic index greater than 5, indicating that the material characteristics have changed from hydrophobic to hydrophilic.
* The results are consistent with the measurement results of settlement characteristics, indicating that settlement characteristics are closely related to surface energy characteristics.

Steam Explosion Equipment

NB800, NB1500 and NB2000 series industrial application steam explosion devices have been used in many companies In terms of actual production, the application industry involves a variety of bio-based products such as fuel ethanol, butanol, xylitol, etc. Covering bioenergy, biofertilizer, biofeed, food processing, biopharmaceuticals, waste treatment, etc.field . The NB2000 series of large-scale instant ejection steam explosion machines has a single cylinder volume of 10 cubic meters and a single machine blasting power of more than 50MW, establishing the company and its technical team as an international leader in the field of steam explosion.

Advantage of OPM Steam Explosion

High Efficiency!

* The pretreated straw is in the form of a slurry that is completely miscible with water, eliminating stratification and floating phenomena, and smoothly realizing the fluidized transportation and fermentation of pure straw;
* When the temperature of the exploded material is lower than 50℃, it can be directly put into fermentation; there will be no blockage or bridging problems in the discharge;
* The anaerobic fermentation degradation time of pretreated straw is shortened from 60 days to three days;
*Compared with thermal blast equipment, the material is sprayed in tens of seconds, resulting in the problem of inconsistent biochemical properties of "premature and late"
* The new technology increases the blasting speed by three orders of magnitude; the blasting power density increases by six orders of magnitude;
* The processing cycle is thus shortened from tens of minutes to 90 seconds, which greatly reduces the pretreatment energy consumption. The steam consumption per ton of material drops from 1 ton to 0.1 ton.
* At the same time, the fast pace of pretreatment has greatly improved the efficiency of the equipment, and the scale of land occupation and equipment investment have also been reduced by 20 times.

Main Features

1. Low Speed of Electric motor
High Torque from low speed will make sure good quality of pellets
2. External Cooling Tower make sure the long operation time each day (occassionally, 24/7 will be acceptable. )
3. Helical Gear box
Std of Accuracy of CNC machining same as Wind turbine gear box Grade 6, less than 0.8μm
4. Fully surrounded air will cool down the ring die and lower down the ash inside pellets.
5. No Bearing inside roller shell (underneath）
Unique patent design, save huge cost of grease and bearing and shorten the breakdown time
6. Innovated bearing system for pellet cutter low down the noise and vibration of pellet mill
7. Several Glass Viewing Window visualize the lubrication system inside the pellet mill.

8. 13 Years experience to develop biomass pellet mill.
9. Local team for after sales technical support.
10. Deploy new technology for production line and consumable parts.
11. Customized design and build
12. Hands on plant operation experience.
13. Monthly Capacity for our pellet mill is at least 30% higher than any other brands of pellet mill with sameoutput ofeletric motor (Energy is saved by 30%)
14. Monthly cost of spare parts (bearing/grease), since we do not have consumption of bearing and grease, the operational cost is only the ring die and roller shell oil seal, aramid packing, etc. Only 1/3-1/2 ofthe the other brands. (refer to the bar chart for consumption of bearing/ grease and service time of roller shell/die )
15. Monthly profit will be higher than other brands of pellet mill of same output.
