Regarding industrial equipment, cryogenic freezers are crucial in many industries that use food, biochemicals, blood tissues, vaccines, and more. These freezers are specially made to use rapid blast or immersion freezing methods to preserve food products.

They are also used extensively in moving/storing/transporting blood and tissue samples. Biotechnology is another key industry that needs a used cryogenic immersion freezer. Here, we take a closer look at this equipment and precision machining of small parts to understand the benefits of both equipment. 

How are Cryogenic Immersion Freezers Deployed?

Used cryogenic immersion freezer are versatile and have many uses, including in biology, chemistry, medicine, food engineering, and medical research. The primary purpose of used freezers in industries is mostly for:   

  • Manipulating high-end metal products
  • Scientific experiments on tissue samples
  • Preserving vaccines
  • Rocket fuel
  • Freezing fresh food products

Thus, these units are used in freezing and cooling biopharmaceutical products such as vaccines, hormones and antibiotics. Besides, this freezing equipment is ideal for use in industries with bacteria enzymes and blood plasma. 

What is Meant by Precision Machining of Small Parts?

Precision machining small parts are equally important as cryogenic immersion freezers are deployed in many industries. But what are these components? 

These small parts are part of a manufacturing process that uses computer-controlled tools to create tight tolerances and high-complexity parts. It's often used to make parts that are difficult to produce by other methods.

How does a used Cryogenic Immersion Freezer Work?

A used cryogenic immersion freezer works similarly to most freezer functions. However, some processes differ slightly. Cryogenic freezing is a substance's fast and precise cooling to extremely low temperatures, such as below -150°C. The cooling rate is speedy, meaning the ice crystals formed are usually tiny, typically in the 10-100 micrometers range. 

Many cryogenic freezers use liquid nitrogen as the refrigerant. At a temperature as low as -196 °C, this cryogenic liquid freezes most substances at lightning speed.

Things to Consider When Buying Used Cryogenic Immersion Freezer

When buying a used cryogenic immersion freezer, you can consider things like: 

  • Quality certificates: Inspect the quality certificates to ensure the product's quality.
  • Physical requirements: Consider the product's packaging, shape, size, and form.
  • Product quality requirements: Consider the product's quality requirements and selling price.
  • Losses: Consider losses in processing and post-thaw handling.

Role of Precision Machining of Small Parts

Machined products are specially made equipment and spare parts that improve the functioning of larger systems. They are primarily small parts used in larger equipment. Hence, the process called precision machining is used. In the case of precision machining of small parts, the process removes excess material from a workpiece while maintaining close tolerance finishes. 

When using precision machining, manufacturers choose material properties that match the machine in which these tiny parts are used. The end product of the more extensive equipment also plays a crucial role in the type of machines they make. 

In effect, precision machining is an important phase of manufacturing and plays a vital role in improving productivity of machines. There are several ways by which such precision machining is implemented and is usually determined by the type of materials in use. 




Used cryogenic immersion freezers play a critical role in diverse industries, especially in the food engineering sector, as they help store raw materials and retain nutrients and freshness. But they are most useful in bio labs and pharmaceutical industries. They are highly used in transporting bacteria enzymes, hormones, antibiotics, blood proteins, and plasma. Precision machining of small parts is essential in enhancing larger machines' functionality and ensuring consistent performance.
