Hickory nut stir-frying method and stir-frying machine

Abstract

The invention relates to a hickory nut stir-frying method and a hickory nut stir-frying machine, which solve the problem of low utilization rate of stir-frying heat of hickory nut. The hickory nut stir-frying method is characterized by comprising the following steps of: performing noncontact heat exchange on airflow formed by high-temperature smoke produced by combustion of a fuel and clean air, heating the stir-fried hickory nut by using the heat exchanged high-temperature airflow, and drying and pre-heating the fuel to be added by using the residual heat of the heat exchanged high-temperature smoke. The machine comprises a combustion furnace and a stir-frying furnace. The machine is characterized in that: the lower part of the combustion furnace is provided with a combustion chamber, the upper part of the combustion furnace is provided with a mazy heat exchange passage, the heat exchange passage comprises a smoke passage and an airflow passage which are mutually isolated, the inlet of the smoke passage is communicated with the combustion chamber, the outlet of the smoke passage is connected with a fuel drying tower, the inlet of the airflow passage is communicated with the outside, and the outlet of the airflow passage is connected with the stir-frying furnace. The invention has high energy utilization rate; and conventional resources are fully utilized, the cost is reduced, and the problem about environmental destruction caused by shells is solved.

Description

technical field [0001] The invention relates to a food processing method and equipment, in particular to a pecan frying method and frying machine, which improves the heat utilization efficiency in the pecan frying process. technical background [0002] Pecan is a nutritious dried fruit. Pecan has two layers of shells, namely the outer shell (fruit cattail) and the inner shell. The edible part of pecan is the core part of the shell (fruit cattail). Pecan processing, The shell needs to be removed first, and then steamed and fried to make finished pecans, which can be peeled (inner shell) for consumption. During the processing, the shell of hickory nuts is usually directly discarded due to its low economic value, which is not only wasted, but also causes environmental damage. In the process of frying hickory nuts, fuel combustion is required for heating. Because the cleanliness of the smoke generated by combustion is poor, it is generally heated outside the frying cylinder, an...
