食品級檸檬酸消費過程中產(chǎn)品枯燥和空氣凈化的特殊請求及設(shè)計特性。 食品級檸檬酸為一種有機化合物， 白色結(jié)晶粉末、色晶體或顆粒，極易溶于水。 食品級氫氧化鉀普遍用于食品、醫(yī)藥、化工及建筑、能源等工業(yè)上。 其產(chǎn)品消費級別又可分為食品級和工業(yè)級。 國內(nèi)**個年產(chǎn)量的食品級檸檬酸消費廠應(yīng)用原有的發(fā)酵工藝，引 進國外的精煉工藝，主要消費無水檸檬酸同時依據(jù)市場的需求，也可消費一水檸檬酸 檸檬酸在常溫常壓下極易吸濕潮解，具有很強的腐蝕性?？菰锵到y(tǒng) 工藝用枯燥系統(tǒng)所處置的空氣都將直接進入到工藝系統(tǒng)流程中，而且是在出廢品階段與產(chǎn)品直接接觸，故系統(tǒng)設(shè)計時不只要保證工藝所需的各項指標。
　　This paper focuses on the special requirements and design characteristics of dry products and air purification during the consumption of food-grade citric acid. Food-grade citric acid is an organic compound, white crystalline powder, color crystal or granule, very soluble in water. Food-grade potassium hydroxide is widely used in food, medicine, chemical industry, construction, energy and other industries. Its product consumption level can be divided into food grade and industrial grade. Domestic food-grade citric acid consumer factories with annual output apply the original fermentation process and import foreign refining process. They mainly consume anhydrous citric acid according to market demand. They can also consume monohydrate citric acid, which is easy to absorb moisture and dehydrate under normal temperature and pressure. It has strong corrosiveness. The air disposed by the drying system used in the process of the drying system will directly enter the process of the process system, and it is in direct contact with the product at the stage of discharging waste products. Therefore, the design of the system does not only guarantee the various indicators required by the process.

　　三氯甲烷廠家通知大家三氯甲烷的操作處置與貯存方式：
　　The manufacturer of trichloromethane informs you about the operation, disposal and storage of trichloromethane.
　　1、操作留意事項。密閉操作，部分排風(fēng)。操作人員必需經(jīng)過特地培訓(xùn)，嚴厲恪守操作規(guī)程。倡議操作人員佩戴直接式防毒面具（半面罩），戴化學(xué)平安防護眼鏡，穿防毒物浸透工作服，戴防化學(xué)品手套。避免蒸氣走漏到工作場所空氣中。防止與堿類、鋁接觸。搬運時要輕裝輕卸，避免包裝及容器損壞。裝備走漏應(yīng)急處置設(shè)備。倒空的容器可能殘留有害物。
　　1. Operational precautions. Closed operation, partial ventilation. Operators must be specially trained and strictly abide by the operating rules. Operators are advised to wear direct gas masks (half masks), chemical safety glasses, anti-poison soaking overalls and chemical gloves. Avoid steam leaking into the air of the workplace. Prevent contact with alkali and aluminium. Handling should be light loading and unloading to avoid damage to packaging and containers. Equipment leak emergency disposal equipment. Empty containers may retain harmful substances.
　　2、貯存留意事項。貯存于陰涼、通風(fēng)的庫房。遠離火種、熱源。庫溫不超越30℃，相對濕度不超越80%。堅持容器密封。應(yīng)與堿類、鋁、食用化學(xué)品分開寄存，切忌混儲。儲區(qū)應(yīng)備有走漏應(yīng)急處置設(shè)備和適宜的收留資料。
　　2. Storage precautions. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Storage temperature does not exceed 30 C and relative humidity does not exceed 80%. Insist on container sealing. Alkali, aluminium and edible chemicals should be stored separately. Mixed storage should not be avoided. The storage area shall have leaking emergency disposal equipment and appropriate collection data.
