Background
The roasted nut food is prepared from fruit and vegetable seeds, nuts and the like as main raw materials, with or without auxiliary materials, by parching, baking (including cooking, frying, water boiling, cooking, high-temperature sterilization) or other processing techniques. Nut roasted food has been written for years. The record is planted as early as the period of business week, and the ancient books such as 'the compendium of materia medica' and 'the Qianjin' are recorded in detail in ancient books such as 'the Qianjin' and the like, so that people can feel 'body and body health' after eating the nut roasted food for a long time. Hundreds of kinds of nut roasted foods are rich in unsaturated fatty acid, protein, carbohydrate, calcium, phosphorus, zinc, iron and other nutrient components, and have certain effects of metabolism, blood pressure regulation and cholesterol reduction. Because of the special nutrition and health care functions and the characteristics of low price and high quality, the nut roasted food is deeply favored by consumers.
Improves the flavoring process, adopts a vacuum negative pressure mode to replace the traditional boiling, soaking and marinating. The vacuum negative pressure cooker is used in principle that roasted seeds and nuts (with shell) are placed in a closed container, and air in the cooker is pumped to form vacuum in the cooker and reach a value close to negative atmospheric pressure. At this time, the air pressure difference exists between the inside and the outside of the shell of the roasted seeds and nuts and the pores of the epidermis are opened, so that the seasoning liquid is soaked in the pot to enter the pulp, and when the atmospheric pressure is restored in the pot, the pores of the epidermis are contracted, so that the effect that the seasoning liquid is remained in the nuts is achieved.
In the current vacuum negative pressure treatment process, directly putting a flavoring agent and nuts into a negative pressure pot body, and performing flavoring treatment through negative pressure treatment; the reagent can't evenly adhere to in the nut to in gradual processing procedure, the reagent can permeate into the shell gradually, leads to the reagent on pot body upper strata not to have sufficient flavoring agent, influences the homogeneity to the nut taste processing.
There is therefore a need to propose a new solution to this problem.
