An exhibition, a witness, Jieyi looks forward to meeting you again next time
Release time:2024-05-31

On May 27th, 2024, the China (International) Dairy Technology Expo opened in Changsha, Hunan.The theme of this conference is "Building New Quality Productivity in the Dairy Industry, Promoting High Quality Development of the Industry". In depth discussions and exchanges were conducted on accelerating the construction of a modern manufacturing system for dairy full chain enterprises, cultivating and strengthening new quality productivity, and promoting high-quality development of the dairy manufacturing industry.

The era of internal competition in the dairy industry is approaching, and only innovation can lead us towards a better future. In the process of deep processing of dairy products, we will continue to work hard to bring higher quality products to customers.

The 30th Annual Conference of China Dairy Industry Association and the 2024 China (International) Dairy Technology Expo, which lasted for three days, came to a successful conclusion on May 29th. Thank you to every new and old friend.

In this exhibition, our new exhibits received a lot of attention, and everyone had sufficient communication and exchange. Many good suggestions will be reflected in the subsequent optimization! Thank you to every customer for your trust and support!

The trip to Changsha has earned friendship and value! Jieyi, set off again!




JE核心产品推荐--膜过滤

膜过滤(Membrane Filtration),是一种与膜孔径大小相关的分离过程,以膜两侧的压力差为驱动力,以膜为过滤介质,在一定的压力下,当产品流过膜表面时,小于膜孔径的水和小分子物质通过而成为透过液,而产品中大于膜孔径的物质则被截留,成为浓缩液,因而实现产品中特定组分的分离和浓缩。

膜过滤工艺广泛应用于乳品、生物、轻化工行业。根据膜的孔径大小,可以分为:微滤(MF, Micro Filtration)、超滤(UF, Ultra Filtration)、纳滤(NF, Nano Filtration),和反渗透(RO, Reverse Osmosis),其在乳品行业的应用如下所示:

MF微滤:可用于牛奶除菌、酪蛋白-乳清蛋白分离;

UF超滤:可用于蛋白质的纯化、牛奶蛋白和乳清蛋白的浓缩;

NF纳滤:可用于牛奶和乳清脱盐、产品浓缩等;

RO反渗透:可用于牛奶和乳清全浓缩、白水回收等。

自2016年推出首款膜过滤设备至今,洁翼流体已经累计售出各类膜过滤中试设备近20台、各类膜生产设备60台,服务乳业客户近50家

跟蒸发浓缩相比,用膜技术对牛乳进行浓缩处理,生产温度一般控制在8-10度的低温状态下,牛奶营养中的热敏感物质,比如,免疫球蛋白、乳铁蛋白以及乳过氧化物酶等,在膜浓缩乳中都能得到较好的保存;同时,对牛乳使用RO膜浓缩技术,产生的副产物就是水,这个水是从牛奶中分离出来的,品质很高,可用于配置各种乳饮料,在减少了浪费的同时提高了产品出成率。所以,RO膜过滤技术深受乳品企业的喜爱!

除了RO膜,根据产品受众的不同,还可以采用不同的膜工艺来对牛乳进行浓缩:

1)针对具有乳糖不耐症的消费人群,可以使用超滤(UF),来排掉牛乳中的部分乳糖;

2)针对婴幼儿的乳制品,可以使用纳滤(NF),在浓缩牛乳的同时,可以排掉部分盐类,防止盐在浓缩奶中的富集;

3)可使用RO-NF-UF组合膜,实现不同组分的富集和分离。
