USED ROSS INDUSTRIES BLC-II

Manufacturer Information
Ross Industries
Ross Industries manufactures food-processing equipment for industrial meat, poultry, seafood, and prepared-food applications. The BLC-II Freezer Tunnel incorporates Ross Boundary Layer Control technology, using high-velocity airflow around the product to promote rapid and uniform heat transfer during continuous chilling and freezing operations.
Description
Available for sale is a used Ross Industries Freezer Tunnel, Model BLC-II, featuring stainless steel construction, continuous conveyor processing, and an approximately 36" wide conveyor belt.
The tunnel incorporates Ross Boundary Layer Control (BLC) impingement technology, designed to increase heat transfer between circulating cold air and products traveling through the tunnel. This configuration can be used for rapid chilling, crust freezing, or individual quick freezing (IQF) of compatible food products.
The system features a modular tunnel design suitable for integration into continuous food-processing lines. Air circulation is powered by 20 HP fan motors equipped with variable-frequency drives (VFDs). The conveyor motors also incorporate VFD control, providing adjustable operating parameters for compatible products and processing requirements.
Electrical requirements are stated as 208V, 60 Hz, 3-phase. The unit is identified by Serial Number 400-4049 and was built in 2001.

Frequently Asked Questions

What type of freezer is the Ross BLC-II? It is a continuous conveyor freezer/chilling tunnel using Ross Boundary Layer Control impingement technology to promote rapid heat transfer.

How wide is the conveyor? The supplied specifications indicate belts approximately 36 inches wide.

Can this tunnel be used for IQF freezing? IQF freezing is a potential application for appropriately configured products and refrigeration conditions. Actual separation and freezing performance should be evaluated for the specific product.

Does the system have variable-speed controls? Yes. The 20 HP fan motors have variable-frequency drives, and the conveyor motors are also equipped with VFDs.

Is the refrigeration system included? The supplied description identifies the freezer tunnel and its motor controls but does not specify a refrigeration compressor package or refrigeration capacity. Buyers should confirm the included evaporator/refrigeration components, refrigerant requirements, and required external refrigeration equipment.

Can Aaron Equipment assist with shipping and logistics? Yes. A modular industrial freezer tunnel can require dismantling, rigging, multiple-component loading, and specialized transportation. Aaron Equipment can assist with dismantling and loading coordination, domestic and international freight, customs documentation, and logistics planning.
