The four major vaporizers lose their energy and help the pharmaceutical industry move forward.

The pharmaceutical industry needs to evaporate a lot of water during the production process, which requires a lot of energy to heat the water to produce steam. Therefore, in the pharmaceutical field, evaporators are widely used. In the pharmaceutical process, what kind of evaporator is more energy-efficient and effective? The following author will bring you several evaporator devices.

Vertical Rotary Evaporator maintains high vacuum

A vertical rotary evaporator is a device that uses a rotary evaporation bottle (flask) to increase the evaporation area and rotates while being placed in a water bath under reduced pressure. The device is heated so that the solution in the bottle diffuses and evaporates. It is an ideal basic equipment for chemical engineering, pharmaceutical industry, universities and scientific research laboratories for the manufacture and analysis of experimental enrichment, drying and recycling.

The equipment uses PTFE and rubber composite seals to maintain a high degree of vacuum; high-efficiency condenser ensures high recovery rate; continuous feeding, digital temperature control of the water bath; reasonable structure, and special materials.

Single-effect alcohol recovery evaporator has high heat transfer efficiency

Single-effect alcohol recovery evaporator The whole plus I heat system has the main characteristics of uniform heating of steam, liquid-liquid flow evaporation, and high heat transfer efficiency and short heating time. Such as the configuration of the hot-pressure pump, more energy saving, low steam consumption, cooling water circulation and other advantages. The material is accelerated and flowed down along the inner wall of the tube to evaporate, adapting to the evaporation and concentration of the liquid with a large viscosity. Single-effect alcohol recovery Evaporator evaporation process under vacuum, both to ensure the hygiene requirements of the material, while ensuring environmental protection requirements, while greatly reducing the evaporation temperature, plus the configuration of the heat pump, some of the secondary steam by the heat pump Re-inhalation and raw steam mixing, both to save raw steam, while the steam through the hot-pump pump spray mist into the heating shell, the rapid diffusion of steam, the liquid heating is mild, so suitable for heat-sensitive material concentration.

The single-effect alcohol recovery evaporator is suitable for evaporating and concentrating foaming materials. Because the material liquid evaporates in the form of a film in the heating tube, vapor-liquid separation is formed, and at the same time, most of the material liquid is pumped away at the bottom of the effector. Part of the feed liquid and all secondary steam enter the separator to strengthen the separation, the liquid process did not form too much impact, avoiding the formation of foam.

Three-effect falling film evaporator realizes automatic control

Three-effect falling film evaporator system consists of various effective heating evaporators, various effect separators, condensers, hot-pressing pumps, sterilizers, thermal insulation tubes, vacuum systems, various effect material liquid delivery pumps, condensate and drainage pumps, operating platforms, and electrical appliances. Instrument control cabinets and valves, piping and other systems.

The equipment features uniform steam heating, liquid-liquid flow evaporation, and high heat transfer efficiency and short heating time. Such as the configuration of the hot-pressure pump, more energy saving, low steam consumption, cooling water circulation and other advantages. Evaporation process is under the action of vacuum, which not only ensures the sanitary requirements of the materials, but also ensures the environmental protection requirements. At the same time, the evaporation temperature is greatly reduced. With the configuration of the hot-press pump, some secondary steam is re-inhaled and mixed with the steam by the hot-pressure pump. It not only saves raw steam, but also because the steam passing through the hot-press pump is sprayed into the heating shell, the steam quickly diffuses, and the feed liquid is heated mildly, so it is suitable for the concentration of heat-sensitive materials.

Three-effect falling film evaporator is suitable for evaporating and concentrating foaming materials. Because the material liquid evaporates in the form of film in the heating tube, it forms vapor-liquid separation. At the same time, at the bottom of the effector, most of the material fluid is pumped away. Part of the feed liquid and all secondary steam enter the separator to strengthen the separation, the liquid process did not form too much impact, avoiding the formation of foam. In addition, the three-effect falling film evaporator can be equipped with a CIP cleaning system to achieve on-site cleaning. The entire equipment is easy to operate and has no dead ends. The configurable automation system can realize the automatic control of the feeding amount, the automatic control of the heating temperature, the automatic control of the discharging concentration, the automatic cleaning control, and can also be equipped with protective measures against sudden power failures and sensitive materials during failures. Other safety, alarm and other automated operations, control.

Falling film evaporator ensures material invariance during evaporation

Falling film evaporators are widely used in the evaporation and concentration of water or organic solvent solutions in the pharmaceutical, food, chemical, light industry and other industries, and can be widely used in waste liquid treatment in the above industries. Especially suitable for heat-sensitive materials, the equipment is operated continuously under vacuum and low temperature conditions. It has high evaporation capacity, energy saving, low operating cost, and can guarantee the material invariance in the evaporation process.

The liquid of the falling film evaporator is added from the top of the evaporator and descends along the wall of the tube under the action of gravity. During this process, the liquid is evaporated and thickened, and the concentrated liquid is obtained at the bottom of the evaporator. Falling-film evaporators can evaporate higher concentrations and have higher viscosity (for example, in the range of 0.05 to 0.45 Ns/m2). Because the solution flows in a single-pass evaporator, the heat transfer coefficient is high, and the residence time is short. , It is not easy to cause deterioration of materials, suitable for handling heat-sensitive materials. The liquid hold-up is small, and the falling film evaporator can be quickly operated according to changes in energy supply, vacuum degree, feed amount, concentration, and the like. Since the process fluid flows only under gravity instead of high temperature difference, low temperature differential evaporation can be used. The falling film evaporator is suitable for the evaporation and concentration of foaming materials. Since the material liquid evaporates in the form of a film in the heating tube, it forms vapor-liquid separation. At the same time, at the bottom of the effector, most of the material liquid is pumped away, only a small part. The feed liquid and all secondary steam enter the separator to strengthen the separation, and the liquid process does not form too much impact, avoiding the formation of foam.
