  • Patent number: 11987096
    Abstract: An indirect heat pump system includes a refrigerant unit, a cold water handling unit, and a hot water handling unit. A cold water inlet of the cold water handling unit communicates with an evaporator; a cold water outlet of the cold water handling unit communicates with the evaporator; the cold water handling unit is connected to a plurality of loads in parallel. A hot water inlet of the hot water handling unit communicates with a condenser; a hot water outlet of the hot water handling unit communicates with the condenser; the hot water handling unit is connected to the loads in parallel; and a plurality of hot water two-way valves are disposed in pipelines of the hot water handling unit and are configured to control the on and off of the hot water in the loads.

  • Patent number: 11903401
    Abstract: A method for increasing the yield of Amadori rearrangement products (ARP) based on a mechanism in which addition of tea polyphenols to deoxyosones inhibits degradation of the ARP. The method includes the following steps: dissolving and mixing amino acid, sugar and tea polyphenol in water, and adjusting a pH value; placing the obtained mixed solution in a reaction flask, and heating the mixed solution at a constant temperature in a water bath to obtain a reaction solution; and performing vacuum decompression dehydration reaction at a constant temperature; after the reaction is completed, using an ice bath to terminate the reaction to obtain a solid reactant, and redissolving the solid reactant in water to obtain an ARP solution. This method promotes the formation of ARP and inhibits degradation of ARP, so that ARP is accumulated and enriched in a large amount (80% and above yield).

  • Patent number: 11802137
    Abstract: A method for preparing an intermediate by a reduced glutathione-indicated amino acid Maillard reaction is provided. The method includes a two-stage reaction at an increased temperature. A reduced glutathione is added after different times of a low-temperature reaction, and a subsequent Maillard reaction is effectively inhibited on a basis wherein a substance is interacted with an intermediate degradation product to reduce a formation of colored substances. Comparing with a browning of Maillard products after a high-temperature stage, a reaction time with a best color inhibition effect is found to be the optimal preparation condition of the intermediate, and the intermediate is prepared in an aqueous medium at a low temperature under this optimal preparation condition. The method uses the water soluble reduced glutathione as a tracer to improve a tracing accuracy comparing to cysteine.
