PS870G Gas specifications

The Middleby Marshall PS870G Gas is a high-performance conveyor pizza oven designed to meet the needs of fast-paced restaurant environments. Known for its exceptional cooking capabilities and energy efficiency, the PS870G has gained popularity in the food service industry, especially among pizzerias seeking to enhance their output and quality.

One of the standout features of the PS870G is its advanced gas-fired heating system. This system utilizes a unique design that maximizes heat distribution and minimizes energy consumption. The oven is equipped with high-efficiency burners, which allow for rapid temperature recovery and consistent cooking results. With a cooking temperature range of up to 600°F, it ensures pizzas are baked to perfection, achieving that ideal crispy crust while maintaining a moist interior.

The PS870G also features a patented design that includes a ceramic stone baking surface. This ceramic stone provides excellent heat retention and even cooking, imitating the traditional stone oven pizza baking method. Additionally, it helps absorb moisture from the dough, contributing to a better texture in the final product. The conveyor system is engineered for smooth transitions, allowing pizzas to move seamlessly through the oven, reducing the chances of burnt edges or uneven cooking.

Another significant characteristic of the PS870G is its user-friendly control interface. Operators can easily set precise cooking times and temperatures, enabling consistent results with every batch. The oven also incorporates a digital display that presents real-time data, helping staff monitor cooking processes efficiently. This technology ensures that high volumes of pizzas can be produced quickly without compromising quality.

Moreover, the PS870G is designed with durability and ease of maintenance in mind. The construction includes heavy-duty stainless steel, making it resistant to corrosion and wear over time. The components are accessible, simplifying routine maintenance tasks and ensuring the oven remains in optimal working condition.

Overall, the Middleby Marshall PS870G Gas is an exceptional choice for any establishment that prides itself on quick service and high-quality pizza. With its innovative technologies, high efficiency, and robust construction, this oven stands out as a benchmark in the commercial cooking equipment market, catering to the demands of modern kitchens. Its ability to deliver top-notch results consistently makes it a preferred solution for pizza operators looking to elevate their culinary offerings.
