The present disclosure relates to a process and an equipment for the clarification of syrup. The process for the clarification of the syrup is simple, efficient and requires less retention / processing time. The process for the clarification of the syrup is flexible, reduces capital cost and operating costs, increases productivity, yields consistent product quality and can be easily scaled up. The equipment of the present disclosure has a simple and compact design and requires a small footprint area and a low capital cost.

The present disclosure provides an equipment and a process for the clarification of feed juice. The equipment offers a compact design with reduced capital and operational costs, requiring a low residence time that minimizes sucrose inversion and heat loss, thereby enhancing clarification efficiency. The process for feed juice clarification requires minimal retention time, ultimately delivering a simplified and cost-effective solution for the cane sugar industry.

The invention relates to a process for treating lignocellulosic biomass, comprising - a) a step of impregnating the biomass with a liquor to obtain impregnated biomass - b) a step of cooking the impregnated biomass, optionally accompanied by a steam explosion, to obtain pre-treated biomass - c) a step of enzymatic hydrolysis of the pre-treated biomass, to obtain hydrolyzed biomass in the form of sugar(s) - d) a solid / liquid separation step of the hydrolyzed biomass in the form of sugar(s) or of the hydrolyzed biomass in the form of sugar(s) and then treated in one or more further steps subsequent to step c) of enzymatic hydrolysis, in order to obtain a separated juice and an unconverted solid residue, - e) a step of recycling at least a part of said unconverted solid residue from step a) of impregnation and / or step b) of cooking.

The utility model discloses a sealed filter with anti -drop function, including the jar body that is equipped with filter jar and jar cover, the inside of filter jar is equipped with several vertical even arrangement's filter plate, the top of filter plate is equipped with detachable connection and is used for preventing filter plate anti -drop subassembly that falls. Realize to filter plate top clamping, effectively prevent filter plate and fall off phenomenon when the pressure sharp change, improve the use effect and security of equipment.

A production method of a sugar solution that includes the following steps (1) to (3) whereby a sugar solution containing concentrated sugar derived from a cassava pulp can be efficiently produced. Step (1): a step for enzymatically hydrolyzing a cassava pulp to obtain a saccharified liquid; Step (2): a step for filtering the saccharified liquid obtained in Step (1) through a separation membrane having a molecular weight cut off of more than 100,000 Da and not more than 300,000 Da to thereby block polymer components derived from the cassava pulp and having a weight-average molecular weight of 10,000-20,000 Da on the non-permeate side; and Step (3) for filtering the filtrate obtained in Step (2) through a nanofiltration membrane and / or a reverse osmosis membrane to recover the sugar solution from the non-permeate side.

The invention relates to the provision of a method for producing a clear sugar beet pre-liming juice and for producing a coagulate removed from the pre-liming juice, and to pre-limiting juice and a fraction containing protein that are provided by means of said method. A decanter centrifuge having an angle between the longitudinal axis of the bowl and the generatrix of the conical portion of 6-10° is used.

The application discloses a floating clear syrup filtering storage tank, which comprises a syrup foaming assembly, a floating clear syrup tank and a filtering frame. The filtering frame is accommodated in an opening arranged on the top surface of the floating clear syrup tank. The syrup foaming assembly is in communication with the filtering frame. The filtering frame comprises a first filter screen plate, a second filter screen plate and a bottom plate. The first filter screen plate and the second filter screen plate are stacked to form the side wall of the filtering frame. The bottom plate is arranged on the bottom surface of the filtering frame. The top surface of the filtering frame is provided with an opening. The device can effectively reduce the insoluble impurities in the syrup, improve the purity of the syrup to more than 85%, and provide better materials (syrup) for the next section of the boiled sugar paste. Meanwhile, the risk of the formation of yellow and black spots in the process of boiling sugar paste is reduced. After the device is used, the obtained finished white granulated sugar can meet the requirements that the number of black spots is less than 4 / m2, the number of yellow spots is less than 5 / m2, the number of yellow and black spots is obviously reduced, the product quality is improved, and the product quality is stable.
