Problems solved by technology

D-ribose is a heat-sensitive substance. Considering energy saving, improving production efficiency and ensuring product quality, the conventional D-ribose concentration process usually causes partial caramel or glucose phenomenon caused by high steam heating temperature. Destroying the characteristics of D-ribose, the quality of D-ribose products cannot be effectively controlled, the process parameters are not easy to control, the heat loss is large, and the energy consumption is high

Embodiment 1

[0034] Inject materials into the concentration tank 4, inject a certain amount of tap water (210-30cm submerged into the coil) into the circulating water tank 1 as circulating water, open the steam condensate valve, drain the remaining internal condensate, and slowly open the steam Intake valve, observe the reading of the thermometer, when the temperature rises to 80°C, adjust the steam outlet trap and steam inlet valve to maintain the circulating water temperature. Open the water inlet and outlet valves of the hot circulating water chamber 6 of the concentration tank 1, so that the circulating water heating system forms a circulation path, and turn on the circulating pump 3, so that the hot circulating water enters the hot circulating water chamber 6, and the cold circulating water enters the circulating water tank 1 for heating Simultaneously open the vacuum pump of the equipment to carry out the vacuum filling operation to the concentration tank 4. After the vacuum degree an...

Abstract

The invention provides a D-ribose concentration apparatus and process for overcoming deficiencies. The process includes three steps of 1 pre-concentration of membrane-treated D-ribose liquid through reverse osmosis, 2 second concentration with a falling film evaporator and 3 final concentration through heat cycle in vitro with a single effect evaporator. The D-ribose concentration apparatus and process can effectively avoid local burnt ribose due to high steam heating temperature, avoid destroying characteristics of D-ribose, effectively control the quality of D-ribose products, be explosion proof or capable of avoiding high temperature operating area, and has the advantages of being easy to control, less in heat loss, high in thermal efficiency and remarkable in energy-saving effects.

Description

technical field [0001] The invention relates to the technical field of D-ribose production, in particular to a D-ribose concentration device and process. Background technique [0002] D-ribose is a very important aldopentose, an important component of genetic material nucleic acid in organisms, and an important intermediate metabolite for organisms to synthesize some amino acids, bases, etc., and has important physiological functions. [0003] D-ribose was first used in semi-synthetic production of vitamin B2. With the development of the D-ribose industry and the in-depth development of its application research, its prospects in the food industry and the pharmaceutical industry have gradually been recognized. D-ribose can be used as a raw material for the synthesis of nucleotide flavor enhancers, such as 5'-IMP, 5'-GMP, etc.; in the pharmaceutical industry, its research and application as a raw material for synthesizing antiviral and anticancer drugs is becoming more and mo...
