Description

The The invention relates to a wet shot mill for wet milling of brewing salt according to the preamble of claim 1.

A generic wet grinding mill is for example from the DE 197 15 210 known. During operation of the known wet grist mill, the brewing salt is first mixed with water in a softening device and thereby softened. In one of the soft device downstream roller assembly with at least two nip rolls, the brewing salt is then digested when passing through a grinding gap between the two nip rolls. The two nip rolls are thereby rotationally driven.

Of the Operation of squeezing rollers in known wet grinding mills conditionally that they are subject to a certain amount of wear. After a certain Operating time is therefore the exchange of nip rolls required, to get the best shot results. In the known wet grinding mills are the squeezing rollers are individually installed in the wet grinding mill. The dismantling the two individual nip rolls requires the dismantling of a Variety of attachments, which causes when replacing of nippers with several days Downtimes of the wet grinding mill must be expected. These downtimes represent a significant cost factor.

outgoing From this prior art, it is therefore an object of the present Invention a new wet grinding mill to propose a deadline for the replacement of the Nippers can be reduced.

These Task is by a wet grinding mill according to the teaching of the claim 1 solved.

advantageous embodiments The invention are the subject of the dependent claims.

The Wet grist mill according to the invention is based based on the idea that the nip rolls work together in one Modular frame are stored and in this way a uniform Forming nip roll module.

This Separate function module can when necessary replacement of squeezing rollers Total in the wet grinding mill be assembled and disassembled. This will make it possible for that new nip rolls in a second functional module intended for replacement finished preassembled and brought to the maintenance wet mill and the exchange of squeezing rollers then through the exchange of the old nip module and the installation of the new or revised and Completely Pre-assembled nip roll module done. The single assembly of Squeezing rollers and the necessary setup work already can during pre-assembly of the replacement nip roller module carried out so that the downtime of the wet shot mill considerably shortened can be.

Especially it is advantageous if the adjustment to the device of the grinding gap and the actuation the adjustment provided actuator also are provided on the module frame of the nip roll module. Through this additional Functional integration into the squeeze roller module can continue setup and adjustment work at the setting before the disassembly of the exchanged Function module be made so that the downtime be further shortened during the actual exchange at the wet grinding mill.

The actuators to operate the Adjustment devices should preferably be designed such that two adjusting devices in pairs with an actuating device can be adjusted.

Which Construction has the module frame of the nip roll module, is basically any. It is particularly advantageous if the module frame closed housing with a feed opening to the feed of brewing salt and a discharge opening to removal of the shot forms. In this way, the squeezing rollers are inside the module rack substantially completely encapsulated, so that damage the sensitive roll surfaces excluded are.

In which way the module frame of the nip roll module mounted in the wet shot mill is, is basically any. Particularly easy and inexpensive, the attachment of the nip module in the wet shot mill, when the wet grist mill has a main frame. On this main frame in turn can then Attachment points may be provided for securing the squeeze roller module are suitable.

In particular, by the use of a main frame in the wet grinding mill, an overall novel structure of the wet grinding mill can be realized. Various functions of the wet grinding mill, for example, the soaking of the brewing salt, the crushing of the brewing salt and the mashing of the brewing salt can be summarized in individual functional modules, so that as a result, the overall function of the wet grinding mill in a few functional modules on shared. These individual functional modules are then designed so that they can be easily attached, for example, in the main frame. As a result, therefore, the main frame forms a basic frame of the wet grinding mill, at which the individual functional modules can be attached to one another successively or next to each other and ultimately only connected to one another at the defined interfaces. In alternative embodiments, in which no main frame is present in the wet grinding mill, the individual functional modules can also be fastened to one another in a self-supporting manner.

In Which functional modules the wet grinding mill is divided, is basically arbitrary. It is particularly preferred if, in addition to the squeeze roller modules with the two nip rolls a Weichkonditioniermodul for soaking of the brewing salt and / or a Gossenmodul for mashing the brewing salt is provided with the addition of water.

at Use of a soft-conditioning module should be preferred a rotatably driven feed roll to include the brewing salt reliable nachfördern in the downstream squeeze roll module.

The Gaskmodul should have a water addition device. To this Way the water addition in the area of the nip roll module can be omitted, so that an extra Water connection of the nip roll module is not required.

Around the wet grist mill with the for supplying the production required quantities of brewing salt is common a storage container, for example, a malt silo, available. In the known wet grinding mills is supported the weight of the malt silo at the upper end of the wet grinding mill and through the individual one above the other arranged parts of the wet grinding mill down into the foundation Lined off, so that all lying in the power flow of the weight Components of the wet grinding mill must be dimensioned mechanically stable. One much simpler construction of the wet grinding mill results when the main frame supporting elements in which the storage container, capturing the force of gravity, supported can be. this leads to As a result, the weight of the storage tank only is still carried by the main frame, whereas those mounted in the main frame Function modules of wet shot mill only still a very low weight load, for example, only caused by their own weight, are exposed.

Of the Use of a main frame simplifies beyond the attachment the drive motors for driving the nip rollers considerably. These Drive motors can in a simple manner on the main frame, in particular on the bottom plate of the main frame. The driving forces of Drive motors can then be transmitted to the nip rollers, for example by means of drive belt.

Of the constructive structure of the main frame is in principle arbitrary. A particularly simple and inexpensive to implement construction arises when the main frame composed of steel profile elements is.

A embodiment The invention is illustrated in the drawings and will be exemplified below explained.

It demonstrate:

1 a wet grist mill in perspective side view;

2 the nip module of the wet shot mill according to 1 in enlarged perspective view.

1 shows the internal structure of a wet grinding mill 01 in perspective side view. From a in 1 malt silo, not shown, the brewing salt passes into an upper insertion opening 02 the wet grist mill 01 , The insertion opening 02 forms the upper end of a Weichkonditioniermoduls 03 in which the brewing salt is soaked by adding water. At the bottom of the soft-conditioning module 03 There is a hidden by the housing feed roller, by means of an electric motor 04 is rotationally driven to provide a reliable conveying motion of the soaked brewing salt.

The soft conditioning module 03 is a nip module 05 downstream. In the module housing forming a closed housing 06 of the nip module 05 are two concealed squeegees installed by means of drive belts 07 and electric motors 08 can be driven rotationally. The two nip rolls are in eccentric rings 09 mounted adjustable and can by means of an actuator, with an adjusting spindle 10 is equipped and by means of a drive crank 20 can be driven, approximated or removed from each other. In the nip roll module 05 The soaked brewing salt is conveyed through the paint gap formed by the nip rolls and thereby digested. After passing through the nip roll module 05 The digested brewing salt reaches the underlying Gossen module 11 where the brewing salt is mixed with additional water. The addition of water into the gutter module 11 takes place by means of spray nozzles, which via a water supply 12 be supplied with brewing water. Part of the gutter module 11 is still a pump 13 that by means of an electric motor 14 is driven and the existing mixture of water and digested malt mixture further into downstream container.

The wet grist mill 01 is designed to be by the successive assembly of the gutter module 11 , the nip module 05 and the soft conditioning module 03 can be built. In this way, the individual functional modules, ie in particular the Weichkonditioniermodul 03 and the nip module 05 Independently preassembled from the other components of the wet grinding mill, transported in the wet shot mill 01 assembled and later dismantled.

For fixing the individual functional modules in the wet grinding mill 01 serves a main frame 15 , which consists essentially of four vertical supports 16 , four horizontal traverses 17 and two bottom plate sections 18 consists. When assembling the wet grist mill, the different electric motors are used first 08 and 14 at the bottom plate sections 18 attached. Subsequently, the Gossenmodul 11 on the bottom plate sections 18 put on and on the two lateral horizontal traverses 17 attached. Thereafter, the nip roll module 05 on the lateral horizontal traverses 17 fitted and with the upper end of the Gossenmoduls 11 connected. On the top of the nip module 05 last becomes the soft conditioning module 03 fitted and with the nip roll module 05 connected. After attachment of the drive belt 07 is the assembly of the wet shot mill 01 essentially completed.

At the upper end of the vertical supports 16 are mounting plates 19 intended. On these mounting plates 19 not shown vertical supports of the above wet grist mill 01 mounted malt silos to be attached and attached. In this way, the entire weight of the malt silo through the vertical supports 16 be derived directly into the underlying foundation, so that on the Weichkonditioniermodul 03 , the nip module 05 and the gutter module 11 only their own weight works.

As far as the wear on the nip rolls makes their replacement required, this can be achieved by the modular design of the wet shot mill 01 be realized in a simple manner. First, the connection between Weichkonditioniermodul 03 and nip roll module 05 solved and the Weichkonditioniermodul 03 slightly raised or removed. Then, the attachment of the nip module on the main frame 15 and / or at the gutter module 11 solved and the nip roll module 05 after removal of the drive belt 07 laterally from the wet grist mill 01 pulled out. Thereafter, a replacement provided as new nip roll module 05 in the wet grist mill 01 be mounted, with the individual functional parts of the new nip roll module 05 completely pre-assembled and pre-adjusted. In this way, the downtime of the wet grinding mill 01 considerably reduced when replacing the nip rolls.

In 2 is the nip module 03 shown enlarged. Due to the compact design of the nip roll module 03 , in which the eccentric rings 09 for adjusting the grinding gap and the required actuating means with the adjusting spindle 10 integrated, most of the assembly and adjustment work required when replacing the nip rolls can be done during pre-assembly of the nip roll module 03 be performed. During the actual replacement of the nip rolls then a worn nip roll module 03 by a replacement or new squeeze roll module 03 Fully pre-assembled and adjusted replaced.
