The Importance of Properly Designed Filter Leaves and Their Effect on Product Quality, Maintenance and Production Costs
Liquid-Solid filtration, simply stated, is the separation of one or more solids from a liquid process stream. It is a “unit operation,” in that it operates on the stream and changes its characteristics. The filter is the process device responsible for this operation. The filter accepts incoming fluid (influent liquor) and discharges the liquor (effluent or filtrate) clear of its previous contaminant. The contaminant remains on the filtering surface within the filter, for either discharge to an approved waste disposal site or saved if of value. The filter, therefore, consists of a vessel which houses the internal filter surfaces. It is these surfaces or filter components that we are concerned with; the most common component being the “Filter Leaf.”

STOCK’s Oscillating Motion Steam-Water-Spray Sterilizers
STOCK America is pleased to introduce a new line of Oscillating Motion Sterilizers to the Food Industry. The retorts are manufactured by SURDRY Sterilization Systems and are offered in both 1400 and 1700 millimeter diameters, up to six cube positions. Our vision was to provide the industry an optimized technology solution utilizing intermittent oscillation, a new concept in sterilization, to overcome viscosity by controlling deflection angle and dwell time of the product. The ability to influence recipe variables provides full control over heat transfer to the product and more uniformed heating which results in decreased process times, exceptional product quality, and increased throughput. By combining oscillating technology with our award winning ICON Sterilization Management System, STOCK America is able to provide a controllable, predictable, and repeatable thermal process saving our customers both time and money.
Six Key Reasons to Convert to Hygienic Internal Gear Pumps for Food and Beverage Product Applications
The Hydraulic Institute has classified more than 30 unique types of rotary Positive Displacement (PD) pumps, each providing different features and benefits. Fortunately for the food and beverage, pharmaceutical/biopharm and personal care product industries, many of these pumping principles are available in hygienic versions, including a new technology - the internal gear pump.

Reducing Contamination Risks of Compressed Air in Food Plants
Any modern food manufacturing facility employs the use of compressed air extensively in the plant. As common as this is, the potential hazards associated with this powerful utility are not obvious and apparent. Food hygiene legislation to protect the consumer places the duty of care on the food manufacturer. For this reason, many companies often devise their own internal air quality standards based upon what they think or have been told is ‘best practice’. This is no wonder, as the published collections of Good Manufacturing Practices (GMP) that relate to compressed air are nebulous and difficult to wade through. Understandably this has led to a significant difference in the quality of compressed air used throughout the industry, with major differences even existing in plants owned by the same company. The goal of this paper is to help make sense of it all.
Analysis of Coalescing Efficiency in Replacemen Filter Elements
High efficiency coalescing filters are often specified when there is a need to protect sensitive equipment that is operated by compressed air. A high efficiency coalescing filter can tame the effects of oil, water, and particulates that are present in virtually all compressed air supply lines. A high quality coalescing filter element will typically have a rated filtration efficiency of somewhere 95% and 99.999+%. The required level of filtration efficiency is dependent upon the quality of the compressed air in the supply line, and the sensitivity of the equipment or process that is connected to the line. For example, when compressed air is used to propel paint to the surface of an automobile body, it is imperative that the compressed air be as pure as possible in order to avoid defects in the painted surface. Therefore, coalescing filters with very high efficiencies are often specified for critical applications.
When designing or executing a construction or renovation project, one factor is often overlooked: soundproofing. This is especially important in projects with multiple components; a factory floor with adjacent office space is an example. In this whitepaper, A M King Construction offers an understanding of how sound travels, and how careful planning during your project’s design phase can eliminate the need for later modifications and ensure each space in your finished project is comfortable, usable for its intended purpose—and doesn’t leave you saying, “Can you hear me now?”
