Deck oven, 9.95 m², 4 levels, 10 openings

LFK-421 Ring Tube Oven 9.95 m² for Increased Production Speed ??Without Enlarging the Front

General Overview

The Logiudice Forni LFK-421 is a ring tube steam oven with a masonry firebox designed for bakeries that want to increase their baking capacity while maintaining a clear and easy-to-read layout. This version of the KAPPA range combines 4 decks, 2 62 cm openings, and a 9.95 m² baking surface. Its 200 cm deep chamber provides a comfortable working surface for baking breads, specialty breads, pastries, and oven-baked goods with even baking on the hearth.

Why this model stands out

The LFK-421 is ideal when you need more capacity than a 4-tier model with a depth of 160 cm, without sacrificing a wider front. Its heating system, using 27 mm diameter annular steam tubes, combined with a masonry firebox and flue, ensures even heat distribution. Refractory cement hearths with metal reinforcement provide gradual heat release, useful for maintaining consistent baking during successive batches.

Key Advantages

• 9.95 m² of baking surface to support sustained bread production.
• 4-deck, 2-door configuration, practical for increasing capacity without multiplying front access points.
• 124 x 200 cm chamber, suitable for bakeries that can utilize greater depth.
• Masonry firebox and flue to support the oven's thermal inertia.
• Independent steam generators positioned under the chambers, with steam evacuation.
• Digital control with 99 programs and automatic start timer, or electromechanical panel depending on the configuration.

Uses and applications

The LFK-421 is aimed at bakeries, production bakeries and CHR laboratories that want to work with a surface close to 10 m² without widening the front installation. It is suitable for the production of standard bread, specialty breads, pastries, and hearth-baked products, with the advantage of a deeper chamber for organizing batches on four levels.

Good to know before choosing

This model is the best choice if you have the necessary depth in your bakery and want to increase capacity without adding a third door. Its external dimensions of 180 x 336 cm must be checked before installation, as well as the available power supply and the intended loading method. Door options can also be important if the oven is used with a lift or loading system.
