For brands entering continuous sterilization, the Hydrolock multi-mode pilot provides process simulation and optimization, supporting R&D retort, saturated steam retort, and steam air retort systems.

Micro-Shuttle

This platform is executed in a two or four basket/cube configuration. The shuttle system is an X, Y application guided by rails bolted to the floor. The rails are fully adjustable and can be positioned to match the elevation of the retort and adapt to irregular floor elevations.

Sweep Type Loader/Unloader

Provided are two modules, one for loading and the second for unloading.

Gantry Type Loader/Unloader

The STOCK Gantry Style Pick and Place Loader/Unloader reduces the labor-intensive tasks of stacking and unstacking heavy trays to and from the retorts.

Conveyor Network

If the desire is to fully eliminate the use of manual trolleys, we can provide Interconnection Conveyors to transport baskets and accurately interface with the Retort Delivery System and Loader/Unloader.

Basket Tracking Option

To be absolutely sure each basket of product went through the retort cycle, basket tracking is available.

Automated Retorts

For Automated Retort Rooms, the retorts are designed to completely integrate with the material handling components.

Automated Product Delivery

Automated Product Delivery Systems provide operator free retort loading and unloading at high production rates by traversing across the floor in front of a bank of retorts to load and unload product.

Automated Sweep Type Loader/Unloader (Rigid Containers)

The Automated Loaders and Unloaders incorporate all the features to provide the fastest sweep speeds for rigid containers in the market within a very robust stainless-steel frame controlled by an Allen Bradley PLC and Color Touchscreen.

Gantry & Robotic Loader/Unloader for Flexible Containers

Automated Flexible Container Loaders and Unloaders use integrated infeed systems with robotic or gantry-style vacuum pick-and-place operations for efficient staging.

Automated Basket Transportation Network with Basket Tracking

The link between the Loader/Unloader and Retort Crate Delivery is the crate conveyor network.

Retort Controls ICON SMS

The ICON is a state of the art control and data acquisition system for control and monitoring sterilization systems, related equipment and general thermal processes.

Retort Controls Add-On Modules

Over the years and at customer request, STOCK has implemented and included many different features to add on to our ICON SCADA control system. We have taken the most requested features and bundled them into software modules. These modules can be added to existing ICON, included with a control system upgrade, or delivered along with new equipment.
