Purification tower and its application in food industry
A purification tower, also known as an absorber tower or a scrubber tower, is an important part of a chemical process and is used for the removal of contamination from liquid or gas streams.It is primarily used for the removal of contaminants from industrial process streams, including wastewater, industrial waste and process off-gases.In the food industry, purification towers are used to reduce the level of contaminants such as sulfur compounds, volatile organic compounds, and various other hazardous air pollutants.
The purification tower is composed of several components, including a tower body, an adsorption or condensing chamber, pumps and valves, filters, and a venturi scrubber. A typical purification tower contains several trays that contain adsorbent materials like activated carbon or silica gel. These materials absorb the contaminants in the process streams and keep them inside the tower.
Purification towers are used in a variety of food processing operations, such as the production of food preservatives, stabilizers, whiteners, flavorings, colors, and texturizers. In addition, they are also used in the curing and preserving of food and beverages. The process involves heating and cooling the air within the tower and adsorbing the contaminants.
The purification tower is designed to reduce the concentration of contaminants in the air to meet pollutant limit requirements set by government agencies. It is important that the tower is capable of capturing the contaminated air, and treating it so that the contaminants can be safely released into the environment.
The purification process is complex and requires special attention to ensure that the tower is operating effectively and safely. Proper maintenance of the purification tower is essential to ensure that it is functioning optimally and is not releasing any contaminants into the environment.
The purification tower is also used in the manufacturing of many food products. For example, it is used in the production of dyes and preservatives, coloring agents, oils, artificial sweeteners and other additives. These materials must be purified before they can be added to food products.
The purification process is an energy-intensive process, and the purification tower requires a significant amount of energy. However, the energy used is usually a fraction of the energy required for other industrial processes.
The purification tower is an essential component of many food manufacturing processes, as it removes harmful contaminants from process streams, and helps to maintain the desired level of product quality. In addition, it is an important part of a company’s environmental policy, as it ensures that products introduced into the environment are safe for human consumption.
