Background technology
Along with the raising of China small towns and life in the countryside level, people pay close attention to more to the diet of oneself, and noodles are popular foods from the ancient capital, and are delicious tasty and refreshing, always very popular.
Change according to humiture, the vermicelli drying can be divided into four-stage:
1. cold wind is decided the bar stage: the task in this stage is the portion of water of removing wetted surface bar top layer, to fix its tissue, gains in strength.Adopt the way of strengthening Air Flow to promote the moisture evaporation, controlling room temperature is 20-30 ℃, forced ventilation, and the time is that 15% of total drying time is 0.6h, moisture drops to 27%～28% by 32%～35%.
2. moisturizing is perspired the stage: the main purpose in this stage is to improve the noodles internal temperature, in order to accelerate moisture transfer velocity from inside to outside.This stage is adopted higher relative humidity when suitably improving temperature, the limiting surface vaporization improves the internal moisture transfer velocity simultaneously.This phase temperature is 35～45 ℃, relative humidity 75%～85%, and accounting for 25% of total drying time running time is 1h, moisture drops to 25% by 27%～28%.
3. moisturizing is perspired the stage: this stage noodles internal temperature raises, and the internal moisture transfer is in a basic balance with the surface vaporization, the temperature that can raise, the humidity that reduces, a large amount of removals of assurance moisture.This phase temperature is 45～50 ℃, relative humidity 55%～60%, and the time is that 30% of total drying time is 1.2h, moisture drops to 16%～17% by 25%.
4. the wet down that the heats up stage: this moment, the noodles self-temperature was higher, so the stage main purpose is reduction face temperature, utilized a small amount of moisture of waste heat evaporation, should note cooling rate, and is generally reasonable with 1 ℃ of 2～3min reduction.It is 1.2h that time accounts for 30% of total time.
Natural drying method is still adopted in modern middle-size and small-size noodles production workshop: area or season in the winds blow gently and the sunshine is warm (temperature is not less than 20 ℃) relative humidity 60%-80% the wetted surface bar is hung on peg i.e. fixed peg, natural air drying.Because drying time is long, so good product quality and be not prone to crisp face.But this kind method hand labor amount is large, and the time is long, is subject to environment temperature, humidity, and the impact in sunlight and season etc., production efficiency is extremely low.The method that adopts the baking room manually-operated oven dry noodles that burn coal is also arranged, and the method cost is higher, and manual control indoor temperature, humidity have caused the large-tonnage product quality low, and production efficiency is low.
