温度控制
Regulating temperature

美国食品和药物管理局(FDA)出版的食品法规,用科学合理的技术规范和法律基础管理了零售和食品行业。食品法规很大一部分是致力于对温度的规定——强制规定的正确温度可以保护食品的安全和质量。FDA的研究显示,最普遍的“越出规范”事件都与由于不正确的制冷,从而导致潜在的危害食物安全有着很大关系。
The U. S. Food and Drug Administration (FDA) publishes the Food Code, a scientifically sound technical and legal basis for regulating the retail and food service segment of the industry. A large segment of the Food Code is dedicated to temperature—mandating the correct temperatures required to protect the safety and quality of food. FDA studies have shown the most common "out of compliance" occurrence is associated with improper cold holding of potentially hazardous food.

一个FDA食品计划调查了食物传染的风险因素,强调了恒一的冷藏温度的重要性。这项调查报告说,许多零售食品商店,餐馆和机构都不符合联邦政府规定的温度标准。结果显示,72%的零售商场的熟食区都有潜在的食品危害隐患,81%的服务餐厅具有潜在食品危害隐患,并且45%小学有潜在的食品安全问题,以上这些都被观察到食品冷藏温度大大超过41华氏度。
An FDA Food Program Survey on foodborne risk factors emphasized the importance of consistent refrigeration temperatures. The survey reported that many retail food stores, restaurants and institutions are not meeting federally mandated temperature standards. Results showed that 72 percent of all potentially hazardous foods in deli departments of retail stores, 81 percent of all potentially hazardous foods in full service restaurants, and 45 percent of all potentially hazardous foods in elementary schools were observed at a temperature greater than 41 degrees F.

为什么温度如此重要
Why it's important

细菌存在于任何地方。他们在土壤,空气,水和我们吃的食物里。当他们有营养素(食品)、湿度、和适合的温度时,他们迅速成长,数量越来越多,以至于某些类型的细菌会导致疾病。细菌在40至140华氏度的温度范围内增长最迅速,在这个 “危险区”,短短20分钟内,一些细菌可以增加一倍。而制冷减缓细菌的生长。一台冰箱设置在40华氏度或者更低可以保护大部分食品的安全。
Bacteria exist everywhere in nature. They are in the soil, air, water, and the foods we eat. When they have nutrients (food), moisture, and favorable temperatures, they grow rapidly, increasing in numbers to the point where some types of bacteria can cause illness. Bacteria grow most rapidly in the range of temperatures between 40 and 140 degrees F, the "Danger Zone," some doubling in number in as little as 20 minutes. Refrigeration slows bacterial growth. A refrigerator set at 40 degrees F or below will protect most foods.

有两种完全不同家庭的细菌:致病细菌——引发食源性疾病,和腐烂菌——导致食品变坏并且发出不愉快的气味,口味和纹理。
There are two completely different families of bacteria: pathogenic bacteria, the kind that cause foodborne illness, and spoilage bacteria, the kind of bacteria that cause foods to deteriorate and develop unpleasant odors, tastes, and textures.

  • 致病细菌可以在40至140温度范围的“危险区”迅速成长,但他们一般不影响味觉,嗅觉,或食物的外观。换言之,人们不能说出病原体的存在。
  • 腐烂菌可在低温下生长,比如在冰箱中。最终他们导致食物发霉,或者产生坏的味觉和嗅觉。大多数人不会选择吃变质食品,但如果他们吃了,他们可能就会生病。它归结为一个质量与安全问题。
  • Pathogenic bacteria can grow rapidly in the "Danger Zone," the temperature range between 40 and 140 °F, but they do not generally affect the taste, smell, or appearance of a food. In other words, one cannot tell that a pathogen is present.
  • Spoilage bacteria can grow at low temperatures, such as in the refrigerator. Eventually they cause food to develop off or bad tastes and smells. Most people would not choose to eat spoiled food, but if they did, they probably would not get sick. It comes down to an issue of quality versus safety.

对那些处理和销售食品者来说,这些细菌都是他们所担心的。为了消费者的健康,为了销售商的产品盈亏,他们保护食品安全是很重要的
Both of these bacteria are a concern to those who handle and sell food. It's important for the health of their consumers that they protect the safety of their food. And it's important for the health of their bottom line that their products do not shrink or spoil.

XDX 可以帮助你
How XDX can help

XDX 的X-Stream阀改善了系统的性能和容量,减少能源消耗和温度的稳定性,从而实现了食物转化的需要,确保食物安全并且减少腐烂和食品收缩。
XDX X-Stream valve technology improves a cooling system's performance and capacity, reducing energy and stabilizing temperature to ensure food safety and decrease spoilage and shrinkage.

传统的冷藏下的腐烂菌的增长速度是35%,增长速度高于同样情况下XDX的增长。并且传统的制冷系统无法满足FDA食品法规规定的产品温度。
The growth rate for spoilage bacteria under conventional refrigeration is 35 percent faster than with the addition of XDX. And refrigeration systems that originally were unable to meet the FDA Food Code for Product Temperature are able to exceed performance requirements following conversion to the XDX system.

XDX帮助传统的系统保持恒一温度研究表明,XDX还可以将产品的保质期时间显著的提高,,当保持温度稳定时,传统食品3天的保质期可以长达5天。
XDX can also deliver a significant increase in product shelf life by helping traditional systems maintain consistent temperatures Studies show that products with a traditional shelf life of three days have a five-day shelf life when the temperature is held constant.

XDX还可以做到:
