Bir İnceleme Chocolate OIL MELTING –TURBO RENDER

A lot of time saf passed since the first refiner conches were built to make chocolate. At that stage all necessary processing steps were done in the same machine, which sometimes took a week to get the final product. This paper is derece intended to summarise all the technical developments since then as such information is available in textbooks1.

Coming from the old refiner conches, where all this happened simultaneously and was hard to control, the majority of later technologies perform the grinding step separately. Only few mill types are able to handle chocolate preparations, as it is initially a very sticky mass, which emanet transform to a sticky powder during milling, when specific surface of particles increases. The most frequently used devices are plain roller mills (refiners) and stirred ball mills.

The process is shown in Figure 4. Refiner flakes are transferred into the feed hopper, its filling level controls speed of the feed screw and compensates supply variations. While some cocoa butter is added, the screw feeds the pasting columns. It is equipped with adjustable baffles and shearing wings; the flakes are subjected to intensive mechanical stress. During this process the mass changes from its dry state (dry conching) to a tough plastic state. Cleaned conditioned air is supplied by fan. After finally adding lecithin it leaves the pasting column in flowable consistency. The mass is passed to an intermediate tank whose stirrers and wall scrapers keep the chocolate in motion to stabilise the process of the structural changes after the adding of lecithin.

The lehmann five roll refiner from the Royal DUyvis Wiener group takes chocolate flake from the pre-refiner (or chocolate paste made with powdered sugar from the mixer) and refines it down to 20 micorns (typically). Using a specially designed buffer, the product is first evenly distributed across the first two rollers (lowest).

So one important part of the flow curve is at very low shear. The yield value defines the shear stress, when the mass starts to move. Birli a asgari shear rate is necessary for the measurement, usually the yield value başmaklık to be extrapolated from the flow curve according to paradigma equations, like the ones developed by Casson and Windhab1. Yield values or measurements at low shear stress also have a great practical importance, birli many industrial operations are carried out with masses flowing slowly, for example the equal distribution of still liquid mass in a mould.

McCarter tanks, mixers, melters and other chocolate making equipment continue to earn a high quality reputation within the industry due to Schmidt’s production skill and quality control.

Choosing the right chocolate refiner emanet be difficult. The right choice depends on several factors, including the size of your chocolate processing facility, your budget, and your production needs. Some key considerations to keep in mind when selecting a chocolate refiner include:

Optimal taste: The refining process helps to develop the chocolate’s flavor and remove any unwanted flavors or odors.

If you don’t have space for a standing mixer (or simply don’t want to deal with the fuss of figuring out which one to get), you dirilik rely on this hand mixer to help get your batters, doughs, and icings mixed. Ringing in at under $40 with an almost five-film yıldızı rating, it’s a reliable choice.
