Sanitary Direct Steam Injection Jet Cookers

Unit Overview:

What is a "SC" Sanitary Steam Injection Heater/Cooker?

The Pick Sanitary Steam Injector is the preferred choice for in-line product cooking, CIP heating or nitrogen gas injection. The Pick SC heats or cooks any water-miscible liquid or slurry instantly on a continuous straight through basis. It can handle slurries containing bite sized particulate such as salsas or stews…with particulate integrity retained!

The Pick Sanitary Heater/Jet Cooker achieves set point temperature instantly and provides a thorough cook of products like starches using its unique, low velocity, variable orifice steam injector and helical flights to ensure intimate and gentle blending of steam and product without high shear and product degradation commonly found with sonic velocity venturi systems. Forget the inherent process inefficiencies and maintenance headaches of traditional batch cooking. The Pick Sanitary Heater meets 3-A sanitary requirements for regulatory compliance with food and dairy applications.  Pick Direct Steam Injection allows you to heat in-line, with precise temperature control and 100% energy efficiency.

Advantages of Pick Sanitary Direct Steam Injection Cooking:
In-Line Cooking

Pick Sanitary Heaters eliminate slow batch processing. Heat, cook or sterilize on a continuous, straight-through basis. The Pick Direct Steam Injection heater processes higher volumes of quality product in less time than any other heating method.

Non-Shearing Action

Helical flights inside the heater body allow a generous, unobstructed flow path for liquids and slurries. Because the Direct Steam Injection process is non-shearing, slurries containing bite-sized particulate can be heated without damage to texture or consistency. Product integrity is maintained, cooking is thorough and fast, and blending is uniform.

Precise Temperature Control

Pick's precise temperature control assures exceptional product quality. With Pick Sanitary Direct Steam Injection, quality control problems common to jacketed kettle cooking or sparging are virtually eliminated. In addition, a separate steam control valve eliminates stem packing leakage (common with close coupled units) and possible product contamination.

Easy Installation and Maintenance

The Pick Sanitary Direct Steam Injection unit can be delivered to you complete and ready to install. Simply connect the system to your steam and product piping and start heating. In comparison to competitive methods, the Pick Heater requires very little effort to clean and maintain. The unit can be easily disassembled in minutes for routine inspection and COP  cleaning. Nothing could be simpler, or faster to maintain.
