中文摘要:
      目的 开发一种多温区的保温箱,并对其温控效果进行研究。方法 通过单因素实验,研究蓄冷剂的摆放位置、外界环境、蓄冷剂与冷鲜产品的质量比等对保温箱温控效果的影响。结果 研究结果表明,侧面摆放结合顶部摆放的方式是保温效果最佳的蓄冷剂摆放方式。在温度为23 ℃、相对湿度为50%的外界环境下,厚度为30 mm的EPP多温区保温箱内,蓄冷剂与冷鲜产品的质量比分别为5∶6(冷藏区)和8∶5(冷冻区)时,保温时间达到24 h以上。保温箱各测试点的保温时间随蓄冷剂质量的增加而延长,且冷藏区和冷冻区的保温时间最长可分别达到44和28 h。建立了外界环境温度-蓄冷剂与冷鲜产品质量比-保温时间的数学模型。结论 该多温区保温箱能够满足冷鲜产品短途快递运输的温控要求。
英文摘要:
      The work aims to develop a multi-temperature insulation box and study its temperature control effects. The influences of the placement of coolant, the external environment and the mass ratio of coolant to cold fresh products on the temperature control effect of insulation box were studied by the single-factor experiment. The research results showed that, the combination of side placement and top placement was the best way to place the coolant with the best heat preservation effect. When the mass ratios of coolant to cold fresh product were 5∶6 (cold storage area) and 8∶5 (frozen area) in EPP multi-temperature insulation box with a thickness of 30 mm in the external environment (temperature: 23 ℃, relative humidity: 50%), the holding time reached 24 h or more. The holding time of each test point of the insulation box prolonged with the increase of the coolant mass, and the holding time of the cold storage area and the frozen area could reach as long as 44 h and 28 h, respectively. The mathematical model of external environment temperature-mass ratio of coolant to cold fresh product-holding time was established. The multi-temperature insulation box can meet the temperature control requirements of short-distance express transportation of cold fresh products.
