Tunnel rice-roll steamer furnace

Abstract

The invention relates to the technical field of large-scale cooking equipment, particularly to a tunnel rice-roll steamer furnace which comprises a cabinet body, a furnace head, an exhaust fan and a steam generator, wherein the steam generator comprises a water tank and a plurality of heating pipes arranged inside the water tank, the bottom of the water tank sinks inward so as to form a combustion chamber, the furnace head is positioned at the lower part of the combustion chamber, a smoke collecting box connected with the exhaust fan is arranged on the side wall of the water tank, the heating pipes are S-shaped, and the upper ends of the heating pipes penetrate out of the side wall of the water tank and then are communicated with the smoke collecting box; the lower ends of the heating pipes penetrate out of the bottom of the water tank to be communicated with the combustion chamber. As flame during burning billows in the heating pipes and the heating pipes are immersed in water, the effect of fire traveling in water is achieved, the heating exchanging effect of water and fire is improved greatly, the heat loss is reduced, and the steam producing efficiency is improved; as the problems of dry burning and water contact of the heating pipes are avoided, the heating pipe corroded speed and the rusting speed are reduced, and the service life of the tunnel rice-roll steamer furnace is longer.

Description

technical field [0001] The invention relates to the technical field of large-scale cooking equipment, in particular to a tunnel-type rice roll oven. Background technique [0002] The rice roll oven is a kind of equipment that uses the principle of steaming rice rolls with high-temperature water steam to make delicious rice rolls. Widely used in hotels, restaurants, eateries, snack bars and other places. Its structure is generally assembled from an upper and lower box structure, with a steam generating device below it and an intestine powder operating room above it. [0003] However, due to the slow generation time of steam in the current existing rice roll ovens, the quantity of powder output is limited, which cannot be used in large quantities, and the production efficiency of rice rolls is low. [0004] In addition, during the working process of the existing heating tube, some segments are located in the water, while the other segment is not submerged in water. In additi...

Problems solved by technology

[0003] However, due to the slow generation time of steam in the current existing steamed rice rolls, the amount of powder produced is limited, which cannot be used in large quantities, and the production efficiency of rice rolls is low.

[0004] In addition, during the working process of the existing heating tube, some segments are located in the water, while the other segment is not submerged in water. In addition, the temperature of the heating tube at the liquid surface is relatively high due to the burning of the flame. Sufficient water vapor, the speed of corrosion and rust is obviously accelerated, the service life is greatly reduced, and the defects are obvious
