灌瓶厂能量转换利用项目的探讨

灌瓶厂在生产过程中,有些工序环节需要吸收热量进行升温,而在另外一些工序环节则需要进行热量释放或输入冷量进行降温。如果在升温和降温工序之间展开适当的能量转换利用,无疑会对充分利用工厂热能及节能降耗工作产生重要的影响。实践证明:实施能量转换综合利用技术,平均投资回收期为一年半,每年可为企业节约能耗总费用达58万元。实为一项值得推广的好项目。

ASEPTIC PROCESSING AND PACKAGING OF MILK

The commercial aspects of aseptic processing and packaging of milk showing only a slow rise in the market are assessed. The paper describes three types of process plant, the indirect plate heat exchanger, indirect tubular heat exchanger and direct steam injection plants and the various advantages are evaluated. Simplification of plants with the removal of de-gassers, flash cooling vessels etc. is emphasized in the modern indirect plant which will heat, cool and homogenize as simply as possible. Differences between operation of a UHT carton dairy and an average bottling dairy are described. ( Editor's summary )     

Automatic Detection of Critical Points in Bottling Plants with a Model‐based Diagnosis Algorithm

The efficiency of bottling plants typically ranges between 40 to 70%. Automatic conditioning monitoring helps to find critical points in a plant and supports the operator in optimizing the plant. But bottling plants are complex lines of several linked machines and currently critical points can only be identified manually. This paper presents a model‐based efficiency analysis tool. It automatically localizes critical points that decrease the efficiency of the whole plant and the tool is adaptable to different plants solely through parameterization. The algorithm compares the behaviour of a plant with an OK‐model of the plant. If there are inconsistencies, the commercial tool RAZ'R finds a failure model that is consistent with the observed plant behaviour, thus localizing the component that causes downtime of the filler. The algorithm succeeds in identifying the cause of the downtime in 90% of the cases. A demonstrator application, which runs on different plants, has been implemented and requires only simple adaptation steps. The algorithm only needs information about the configuration of the plant and the production data, which normally exists in automated plants. In the future, it is expected that the project partners will integrate the algorithm with their PDA‐systems, such that the model‐based analysis will help to increase the efficiency of bottling plants.     

Noise risk assessment in a bottling plant of a modern Italian winery

In the wine industry, bottling is a phase of the production cycle characterized by high levels of noise, mostly owing to repeated collisions between the bottles. In Italy, the Law Decree 81/2008 defined the requirements for assessing and managing noise risk, identifying a number of procedures to be adopted at different noise levels to limit worker exposure. This study was aimed at evaluating the equivalent and peak noise level inside the bottling plant area of a modern Italian winery. In particular, the influence of the working capacity (number of bottles produced per hour) on noise levels was evaluated. Three test conditions were considered: T1 with a working capacity of 4000 bottles/h; T2 with working capacity of 5000 bottles/h; and T3 with working capacity of 6000 bottles/h. Fifteen measurement points were identified inside the bottling area. The instrument used for the measurements was a precision integrating portable sound level meter, class 1, model HD2110L by Delta OHM, Italy. The results indicated that, as the bottling plant working capacity increased, noise levels increased. The measured sound levels exceeded the limits allowed by the regulations in all of the test conditions. Values exceeding the threshold limit of 80 dB(A) were recorded, increasing to a maximum value of 95 dB(A) in test T3. In this case, the operator working along the bottling line was obliged to wear the appropriate personal protective equipment. Copyright © 2014 The Institute of Brewing & Distilling

The employee view

Over a span of roughly 30 years the dairy industry has been steadily advancing in its technology. Two main areas in this advance have affected the employee. They are the development of high speed processing and bottling, and the steady progress of the carton in gradually speeding up production and the use of less and less manual labour.
The high speed bottling plant has on the plus side done away with a lot of manhandling of a heavy product and helped to improve the pay with less hours worked. On the minus side, a lot of processing jobs were lost. These things had relatively little effect on the milkman.
Cartoning has a plus side for processing workers in that it replaced some jobs which otherwise have been lost. For retail milkmen the carton that was first produced for very good reasons is now, with improved productivity and the interest shown in it by the supermarkets, posing a threat to retail distribution which would make the processing job losses minimal by comparison.
