Importance of Drying During Production

 


At a certain point, each production method encounters the problem of moisture. The causes of moisture will vary widely and therefore the consequences of moisture are usually terribly completely different. However, the answer continually comes all the way down to an equivalent thing: remove the maximum amount moisture as possible. Drying or blow-off solution will prevent a lot of your time, energy and cash.

Possible causes of moisture?

The causes of moisture formation will vary widely. Our expertise shows that these causes are often divided into 3 broad classes:

  1. Cooling – several product are cooled. Typically because the last step during a sterilization or pasteurization method. Water is usually used for this purpose, leaving water droplets on the product. For example: prepared meals, cans, pet food, other examples are extrusion of plastics or rubbers.
  2. Cleaning – After production, the product are usually cleansed, washed or rinsed. Once again, water droplets remain behind. For example: beer, jam, sauces, and soft drinks.
  3. Steam – To sleeve products, they are often placed in a steam tunnel. The excess water must be removed. For example: fruit juices.

Possible problems due to moisture?

  1. Contaminated environment – First of all, moisture contaminates the space in which the production process takes place. Moisture is difficult to control. Especially in places where hygiene is of great importance, (polluted) water can make the whole environment dirty and dangerous (slippery).
  2. Ink spill – Printing on damp products is not possible. Many products require a production date or an expiry date. As long as the product is still damp, the inkjet codes will run out and become illegible.
  3. Non-adhesive labels – Even if you want to stick labels on the products, this will not work as long as they are damp. The glue from the labels can only stick on completely dry surfaces.
  4. Damaged machines – After all, many (packaging) machines are not resistant to water. Wet products can leave moisture in your machine and cause it to break down faster.
  5. Failing control equipment – Production processes are often checked at different times and on different parameters (such as speed, weight, etc.). The cameras, metering cells and different equipment used for this purpose sometimes don’t perform properly once the product remains coated with water droplets. Or the equipment could sustain water damage.
  6. Mould formation – Food is often packed in plastic. If the product is still wet, the moisture evaporates and mould can form.
  7. Cracking cardboard – Another ordinarily used method of packaging is cardboard. Cardboard, too, isn’t resistant to water and often tears when it gets wet.

Different Types of Sterilization Process

  Sterilization can be accomplished by an amalgamation of heat, chemicals, irradiation, high pressure and filtration such as steam under pressure, dry heat, ultraviolet radiation, gas vapour sterilants, chlorine dioxide gas etc. Successful sterilization strategies are necessary for working in a lab and negligence of this could lead to severe consequences, it could unexpectedly cost a life. So what are the more frequently utilized methods of sterilization in the laboratory, and how do they work? The Sterilization is conveyed out by the methods according to requirement. The methods are: 1. Moist Heat Sterilization 2. Dry Heat Sterilization 3. Gas Sterilization and Others. Moist Heat Sterilization:  Moderate pressure is utilized in steam sterilization. Steam is utilized under pressure as a means of accomplishing an elevated temperature. It is dominant to confirm the accurate quality of steam is utilized in order to keep away the problems which follow, superheating of the steam, f...

Electromagnetic Energy in Food Processing

  The use of electromagnetic energy in food processing is considered with respect to food safety, nutritional quality, and organoleptic quality. The results of nonionizing radiation sources such as microwave and radio-frequency energy and ionizing radiate on sources. Nonionizing microwave energy sources are more and more used in home and industrial food processing and are well-accepted by the end users. But, even though new-fangled Food and Drug Administration approval of low and intermediate ionizing radiation dose levels for grains and further plants products. Microwave  and  radio frequency  energy are allotments of the electromagnetic spectrum that can redeem heat to foods selectively and systematically. Explicitly, microwaves interrelate with water in foods to heat preponderant those allotments that are wet. End users are usual with microwave ovens as household appliances used to warm and cook foods, defrost frozen foods, and pop popcorn. On an industrial scale,...

Sterilization Method in Chemical and Psychological

  Sterilization indicates to any process that removes, kills, or deactivates all compositions of microorganisms such as fungi, bacteria, viruses, spores, unicellular eukaryotic organisms such as Plasmodium, etc. Sterilization can be attainted through diverse means, including heat, chemicals, irradiation, high pressure, and filtration.   Sterilization   is distinct from disinfection, sanitization , and pasteurization , in that those methods reduce rather than destroying all forms of life and biological agents present. After sterilization, an object is resorted to as being sterile or aseptic. Chemicals are also accustomed for sterilization. Heating provides an infallible way to exterminate objects of all transmissible agents, but it is not always suitable if it will vandalize heat-sensitive materials such as biological materials, fiber optics, electronics, and many plastics. In these circumstances chemicals, either in a gaseous or liquid form can be used as sterilants. Whil...
