|PACKAGED IQF SPIRAL FREEZER|
DESIGNED FOR QUALITY
Completely factory assembled, and tested prior to shipping.
The spiral conveyor is constructed with NON-CORROSIVE aluminium. Refrigeration coils are constructed with aluminium or hot-dipped galvanized steel to maximize heat transfer efficiency and length of operation Intervals. The frigid air is delivered with aluminium high eff iciency air foil tan wheels directly driven by high efficiency motors. Air flow baffling is constructed of heavy gauge aluminiurn for maximiurn air channeling and optimum heat removal from the product. The freezer enclosure is constructed with 5 inch thick foamed in-place urethane laminated with stainless steel. All of the stainless steel joints are seal welded. The spiral drives are driven by a variable frequency drive for a smooth and safe control speed to protect the system from over-tension and malfunction. The freezer is built to USDA, FDA, OSHA and CSA standards
Advanced’s freezers are equipped with all stainless steel heavy-duty spiral telescopic belting. The belt can be telescoped and extended to change the pitch of the links. During operations the extended belt approaches the rotating drum with one side of the belt telescoped in, causing it to spiral up the rotating drum. The spiral belt is made of all stainless steel 304 material.
Belt Supports and Spiral Frame
The belt is supported by all STAINLESS STEEL rails, protected by U.H.M.W. polyethylene wear strips. The spiral frames are also all STAINLESS STEEL constructed.
Spiral Freezer Drum
The drum is constructed with all aluminum structure materials, protected with U.H.M.W. polyethylene wear strips for many years of smooth maintenance-free operation.
Belt Take Up
The spiral belt system is equipped with automatic belt tensioned to ensure smooth belt operation in various temperatures ranges and wear.
The freezer drive system is located at the topside of the spiral conveyor, and is electrically driven by a variable frequency drive gear motor. The proper belt takes up tension id driven by a second gear motor directly linked to the drum motor designed to operate at an overdrive speed ratio. When varying the drive motor, both belt and drum speeds change proportionately to compensate for the overdrive speed ratio.
For protection against over sized products, a limit switch is provided at the in feed end of the freezer. For protection against over-tension of the belt, a safety belt tilt switch is located at the top tier of the freezer to protect each tie
The evaporator coil is made of all-aluminum fins and tubing for freon or ammonia re-circulation, flood, or direct expansion service. The fin spacing, which varies with the depth of the coil, is wide at the air inlet side and narrow at the discharge side. This ensures even frost built up on the coil without restricting airflow and thus maintains the maximum performance of the freezer operation time. The coil is furnished with liquid, suction, hot gas and water connections for easy hook up.
Air Flow System
The air is provided by all-aluminum high performance airfoil propeller fans directly driven by high efficiency motors. The single pass turbulent airflow passes through each tier horizontally and returns to the coil in a horizontal circular loop pattern. This is the most efficient airflow pattern to obtain maximum heat transfer of the product.
Electrical Control Panel
The electrical control panel is all stainless steel constructed and mounted on the outside wall of the enclosure. The control panel is equipped with switches and motor starters, and are all fused to protect each motor. The electronic retention time meter and the digital temperature read out will be provided as options the mechanical temperature gauge is provided as standard.
The freezer enclosure is made of heavy gauge stainless steel sheet complete with internal steel structural supports for strength. The enclosure insulation is 5” thick density foam urethane for maximum efficiency. Wall and floor panels are SEAL-WELDED together on the inside. Large stainless steel access doors at all necessary locations allow for easy cleaning and maintenance.
Freezer Internal Washing Manifold and Belt Washer
Manifold Freezer shall be equipped with internal center drum wash manifold c/w with spray nozzles for washing freezer interior and belt
