Automation Enhancement

/in /by

The paperless recorder LOGOSCREEN TFT display represents a new generation of paperless recorders from JUMO that stand out through their modular design for the acquisition of measurement data (3 to 18 measurement inputs can be implemented internally), their innovative operating concept and high standards of security to prevent unauthorized access and manipulation of the stored data.

In the LOGOSCREEN data can be visualized in process images as measurement curves, as a bar graph or in alphanumerical form. Powerful PC programs are available for analyzing and evaluating the archived data, and for configuring the LOGOSCREEN. This is also coupled with compact flash card & USB interfaces. This has made easier control for operator to see multiple process values on screen at a time & taking timely action on deviations. Key features are

  • Easy operation by control knob or touchpad
  • Measurement data storage on CompactFlash memory card or USB memory stick
  • Automatic read-out of data through the PCA Communications Software (PCC)
  • Interface to SCADA systems,
  • PLC controls and PC systems
  • Integrated web server
  • Simultaneous recording of up to
  • 3 batch reports
  • Batch control (start, stop, texts) through
  • Barcode reader
  • Modbus master function
  • ATEX approval with stainless steel front

Milk Air Elimination at Reception

/in /by

In Pakistan dairies are small; collection is confined to nearby farms. The micro-organisms in the milk could be kept under control with chilling. Milk during handling pumping absorbs lots of air in it which will disturb sensory parameters of milk like taste, odor & color. Dairies have special milk receiving areas to control the entry of the milk coming from farms. Milk on reception passes through air eliminators that collects the air from the incoming milk through various means of vacuum creations. This enhances milk quality parameters before processing.

The presence of undesired air and gases in liquid food products frequently leads to deterioration in product quality in physical, chemical and sensory terms. All product processing, which for example includes pumping and various mixing processes, will automatically disperse or/and incorporate air into the mixture. In addition, some raw materials contain gases, most of which are not desirable.

The main objectives for air elimination, deaeration and deodorizing of food products are: improved product quality, increased shelf life and storage stability, reduction of overall production costs, and improved process control

The Milk Reception Unit receives milk and liquid milk products for a milk processing plant. The unit deaerates, measures, and pumps the product for buffering or further treatment. In Pakistan air elimination process is getting popular at dairies in receiving the milk from other farms.

Homogenization Importance

/in /by

In dairy processing homogenization has a vital importance for improving dairy finished products stability in quality. But homogenization is becoming compulsory in other industries too.  In the cosmetic industry, homogenization provides more stable, uniform emulsions with higher performance characteristics. In the pharmaceutical industry, the primarily mechanical nature of the homogenization process provides direct access to enzymes, proteins, liposomes and intracellular active substances without having to utilize chemical lysis of the membrane. Other effects are seen in the preparation of stable solutions of products with different physical characteristics (proteins, creams, solutions of active principles, oils, vitamins). The increase in the surface area of the micronized particles is also of interest to the chemical and petrochemical industries because of the resulting enhancement of transformation reactions. This also creates further advantages, such as: noticeable reduction of catalysing substances, intensification of pigment colour, enhanced use and reduced quantity of additives, viscosity control of finished products. Crushing of active principle particles generates an increase in surface area, thus enhancing preparation assimilation.

Here is a list of some products from the cosmetic, chemical, pharmaceutical and petrochemical  industries that may be homogenized:

Adhesives – Starches – Antibiotics – Cellulose and derivatives – Waxes – Colorants – Cosmetics – Beauty creams – Toothpaste – Detergents – Emulsifying disinfectants – Emulsions – Greases – Inks – Latex – Liposome suspensions – Lotions – Shoe polish – Emulsifiable oils – Lubricating oils – Pigments – Perfumes – Proteins – Resins – Soaps – Syrups – Paints – Vitamins
