每種干燥設(shè)備都有特定的適用范圍,每種材料都能找到幾種能滿足基本要求的干燥設(shè)備,但合適的只有一種。如果選型不當(dāng),用戶不僅要承擔(dān)不必要的一次性高采購成本,還要付出整個使用壽命的沉重代價,如效率低、能耗高、運(yùn)行成本高、產(chǎn)品質(zhì)量差,甚設(shè)備根本無法正常運(yùn)行。
Each drying equipment has a specific scope of application, each material can find several kinds of drying equipment that can meet the basic requirements, but only one is suitable. If the model is not selected properly, the user not only has to bear the unnecessary one-time high procurement cost, but also has to pay the heavy price of the whole service life, such as low efficiency, high energy consumption, high operating cost, poor product quality, and even the equipment can not operate normally.
以下是干燥設(shè)備選型的原則,很難說哪一項(xiàng)或哪幾項(xiàng)是重要的,理想的選型必須根據(jù)自己的條件有所側(cè)重,有時折中是必要的。
The following is the principle of drying equipment selection, it is difficult to say which one or which one is important, the ideal selection must be based on their own conditions, sometimes compromise is necessary.
1.適用性——干燥設(shè)備必須適合特定物料,滿足物料干燥的基本使用要求,包括物料的良好處理(進(jìn)料、輸送、流化、分散、傳熱、出料等)。),并滿足處理量、脫水量和產(chǎn)品質(zhì)量的基本要求。
1. Applicability - the drying equipment must be suitable for specific materials and meet the basic requirements for drying materials, including good treatment of materials (feeding, conveying, fluidization, dispersion, heat transfer, discharging, etc.), And meet the basic requirements of processing capacity, dehydration capacity and product quality.
2.干燥速率高——就干燥速率而言,物料在對流干燥時高度分散在熱空氣中,臨界含水率低,干燥速度快,也是對流干燥。不同的干燥方法有不同的臨界含水率和不同的干燥速率。
2. High drying rate - in terms of drying rate, materials are highly dispersed in hot air during convection drying, with low critical moisture content and fast drying speed, which is also convection drying. Different drying methods have different critical moisture content and different drying rate.
3.耗能低——不同干燥方法耗能指標(biāo)不同。
3. Low energy consumption - different drying methods have different energy consumption indexes.
4.節(jié)約投資——完成同樣功能的干燥設(shè)備,有時成本差異大,應(yīng)選擇低者。
4. Saving investment: for drying equipment with the same function, sometimes the cost difference is large, so the lower one should be selected.
5.運(yùn)行成本低——設(shè)備折舊、能源消耗、人工費(fèi)、維護(hù)費(fèi)、零部件費(fèi)等運(yùn)行費(fèi)用盡量便宜。
5. Low operation cost: the operation cost such as equipment depreciation, energy consumption, labor cost, maintenance cost and parts cost should be as cheap as possible.
6.優(yōu)先選用結(jié)構(gòu)簡單、備件供應(yīng)充足、可靠性高、使用壽命長的干燥設(shè)備。
6. The drying equipment with simple structure, sufficient supply of spare parts, high reliability and long service life is preferred.
7.符合環(huán)境保護(hù)要求,工作條件好,性高。
7. Meet the requirements of environmental protection, good working conditions and high safety.
8.選型前能做出物料的干燥實(shí)驗(yàn),深入了解類似物料已經(jīng)使用的干燥設(shè)備(優(yōu)缺點(diǎn)),往往對恰當(dāng)選型有幫助。
8. It is helpful to make drying experiments of materials before type selection, and deeply understand the drying equipment (advantages and disadvantages) used for similar materials.
