The invention discloses a method for realizing circulating clarification utilization of sugar industry filter mud based on calcination, which comprises the following steps: filter mud drying: scattering and drying wet filter mud to obtain dry filter mud; suspension flash burning: mixing the dry filter mud with limestone powder, calcining by utilizing secondary hot air in a suspension cooling process, removing organic matters in the dry filter mud and partially decomposing calcium carbonate in the mixed material; performing fluidized bed roasting: introducing high-pressure air into the mixed material subjected to suspension flash burning treatment to enable the material to utilize waste heat of the material in a boiling state to complete deep decomposition of calcium carbonate so as to obtain a high-temperature finished product; suspension cooling: cooling the high-temperature finished product to obtain a low-temperature finished product; digesting: digesting a low-temperature finished product to prepare lime milk; and flue gas reutilization: the CO2-containing flue gas generated by suspension flash burning is sequentially used as a drying heat source for filter mud drying, and is used for a sugar juice clarification and carbonation process after being purified. According to the invention, the pollution problem is solved, resource utilization is realized, the use of limestone is reduced, the flue gas heat of the system is fully utilized, and the energy consumption is reduced.

This invention relates to fruit juice flocculants, a chitosan-coffee grounds nanoparticle composite, its preparation and application, comprising the following steps: 1) Obtaining coffee grounds powder: drying and sieving coffee grounds to obtain the desired coffee grounds powder; 2) Dissolving the coffee grounds powder in water, heating, filtering, collecting the filtrate, passing it through a D101 macroporous resin column, eluting with water, dialyzing and drying the eluent to obtain coffee grounds nanoparticles; 3) Mixing a chitosan aqueous solution (chitosan:water) at a mass ratio of 1:100-400 with the coffee grounds nanoparticles and adding it to a reaction vessel for hydrothermal reaction; dialyzing and drying the resulting solution to obtain the chitosan-coffee grounds nanoparticle composite. This invention aims to use nanoparticles with good biocompatibility, low dosage, significant flocculation effect, good antioxidant properties, and visibility to modify chitosan, synthesizing a novel flocculant and providing a new approach for fruit juice clarification.

The invention discloses an acid-resistant low-temperature high-activity pectate lyase mutant as well as a preparation method and application thereof, and belongs to bioengineering and enzyme engineering. The amino acid sequence of the pectate lyase is as shown in SEQ ID NO: 1, and the mutation site in the mutant is at least one of N52A, K95A, E166L, Q212L, E280I or S307D. The pectate lyase mutant disclosed by the invention can be used for clarifying fruit juice, and particularly can be used for efficiently hydrolyzing pectin in the fruit juice under the conditions of acidity (pH 3.5-5.5) and low temperature (10-25 DEG C), so that the light transmittance of the fruit juice is improved, the viscosity is reduced, and the juice yield is increased.

This invention discloses a continuous reaction device and method for efficient clarification of sugarcane juice, belonging to the field of sugarcane juice clarification. It includes a housing with a cover plate on top. An addition tube is integrally formed on the top of the cover plate, and a gear is fixedly connected to the outer wall of the addition tube. A filter cylinder is fixedly installed at the bottom of the cover plate, with its bottom tube extending into the interior of the housing. A bracket is detachably installed on the top right side of the housing via bolts. A motor is fixedly connected to the inner side of the bracket, and a gear is fixedly connected to the bottom end of the output shaft of the motor. This device effectively solves the technical problems of poor filtration effect, easy adhesion of sugarcane juice to the filter residue surface leading to low recovery rate, easy clogging of the filter screen, and difficulty in separating and using sediment from sugarcane juice in existing sugarcane juice clarification processes. Through the dual filtration structure of the filter cylinder and the clarification filter cloth, the purity of the clarified sugarcane juice can be significantly improved, achieving deep purification of the sugarcane juice.

This invention discloses a denitrification process for preparing sweet white wine. The process steps are as follows: Grape pretreatment: Select fresh white grapes of uniform ripeness, manually remove rotten and diseased grapes, destem, crush, and extract juice using a press. Collect the juice and filter to remove pomace to obtain initial grape juice; Juice clarification: Quickly cool the initial grape juice to 3-5°C, add 30-35 mg / L pectinase and 40-60 mg / L sulfur dioxide, stir evenly, and let it stand for clarification for 24-36 hours. Take the supernatant as the fermentation liquid; Primary denitrification fermentation: Transfer the fermentation liquid to a fermentation tank, raise the temperature to 12-15°C, inoculate with wine yeast, control the fermentation temperature at 16-18°C, and stir 2-3 times a day; When the alcohol content of the fermentation liquid reaches 3.5% vol, add 0.4-0.5 g / L of chitosan-benzene complex. This invention's staged denitrification avoids the yeast stress response caused by adding a large amount of adsorbent at once, and significantly enhances the microbial stability of the wine.
