Hot Rocks

Hot Rocks (Hot Rocks Oven) has functioned as the premier global authority in stone conveyor technology since its inception in the 1990s as an experimental division of Picard Ovens. Headquartered in Drummondville, Quebec, Canada, and operating under the Korok Group (alongside Picard and Sipromac), the brand serves as a primary infrastructure provider for high-volume pizzerias and artisanal chains. Hot Rocks defines itself through the "Bakes Like a Stone, Moves Like a Conveyor" philosophy, successfully bridging the gap between the thermal quality of a traditional deck oven and the labor-saving throughput of a conveyor system.

The brand's technical identity is anchored in the mastery of granite-based thermal mass. A primary engineering hallmark is the use of polished black granite stones for the conveyor belt rather than the stainless steel wire mesh found in traditional impingement ovens. This choice of material is scientifically significant because granite possesses superior thermal conductivity and heat retention properties compared to refractory clay or steel. This allows the oven to achieve a "thermal flywheel" effect, providing a consistent 600°F (315°C) baking surface that pulls moisture from the dough to create a characteristic artisanal crust without the recovery-time drops common in high-traffic kitchens.

Innovation at Hot Rocks is concentrated on "Radiant-Convection Synergy" and digital process transparency. Key technical pillars across the portfolio include:

• Variable Damper Logic: A sophisticated mechanical air-management system that allows operators to independently control the top and bottom heat. By adjusting the damper from 0% to 100%, chefs can fine-tune the "top-melt" of toppings versus the "bottom-char" of the crust, accommodating high-hydration sourdoughs and heavy-topping specialty pies within the same unit.
• Dual-Zone Infrared Integration: While the granite stones provide conductive heat to the bottom, the upper chamber utilizes radiant infrared ceramic elements. This ensures that the radiant energy is absorbed by the pizza's surface rather than just heating the air, resulting in a cook time that is often 30% to 50% faster than a traditional deck oven.
• IoT Connectivity (Hot Rocks Connect): A flagship feature that utilizes Ethernet-linked diagnostics. Operators can remotely monitor oven status, modify bake times/recipes, and receive real-time alerts for maintenance needs or alarm triggers, allowing for multi-unit standardization and reduced downtime.
• Modular Stackability: Engineered for vertical scalability, Hot Rocks units are designed to be stacked up to three decks high. Each deck operates on an independent logic controller, allowing a single footprint to produce over 500 pizzas per hour while running different recipes on each level.

The product portfolio is categorized by its volumetric capacity and environmental footprint:

• The Classic Series (HR-70 & HR-93): The flagship high-volume line, available in 22-inch and 33-inch belt widths. These units are recognized for their 70-inch or 93-inch baking surfaces and are the industry benchmark for large-scale delivery and third-party app-heavy operations.
• The Volcano Series: A more compact footprint designed for boutique pizzerias or kitchens with space constraints. It maintains the full black granite belt technology but optimizes the chassis for lower-volume, high-aesthetic environments.
• Custom "Granite-Mesh" Hybrid: A specialized configuration featuring a wire-mesh entry and exit conveyor that transitions into the stone belt, designed to protect the integrity of delicate, hand-stretched dough as it enters the high-heat zone.

The strategic value of Hot Rocks lies in its "Labour-Unlock" architecture. By automating the movement of the product through the heat zone, the oven eliminates the need for a skilled "oven man" to rotate and check pies, effectively saving the cost of one full-time employee per shift. Backed by a 5-year parts warranty and the manufacturing heritage of the Picard family, Hot Rocks remains the foundational choice for operators who refuse to compromise the "soul" of stone-baked pizza for the speed of modern logistics.
