Not macht erfinderisch

Wirtschaftsjournalist und langjähriger Mentor der TOP 100, Ranga Yogeshwar: „Das Corona-Virus hat mit ungeheurer Wucht unsere Welt erfasst. Es ist eine Krise, aber im Deutschen gibt es das Sprichwort „Not macht erfinderisch“. Und gerade Innovatoren sehen in Krisen auch manchmal eine Chance. Bei TOP 100 geht es um Innovatoren, es geht darum zu zeigen wie diese Unternehmen den Mut haben sich neu zu erfinden, Neues zu entwickeln und damit eben auch zu einem leuchtenden Beispiel für andere werden.“
 

Jurymitglied TOP 100 Dorothee Bär,

Staatsministerin im Bundeskanzleramt,

„Der innovative Mittelstand ist die treibende Kraft des Erfolgsmodells „Made in Germany“ und TOP 100 hilft die Unternehmen sichtbar zu machen, die mit ihrer Innovationskraft zu dem wirtschaftlichen Erfolg Deutschlands beitragen und die Digitalisierung als Chance sehen.
 

Auszeichnung für die innovativsten Mittelständler Deutschlands

Zum 27. Mal wurden die TOP 100 ausgezeichnet, die innovativsten Unternehmen des deutschen Mittelstands. HOF nahm zuvor an einem anspruchsvollen, wissenschaftlichen Auswahlprozess teil. Untersucht wurden das Innovationsmanagement und der Innovationserfolg.

Die von Prof. Dr. Nikolaus Franke als wissenschaftlichem Leiter entwickelte Systematik räumte dabei produzierenden und dienstleistenden Unternehmen dieselben Chancen ein und berücksichtigte auch die jeweiligen Unternehmensgrößen. In dem unabhängigen Auswahlverfahren überzeugte HOF mit seinen rund 270 Mitarbeitern besonders mit seinem Innovationserfolg.
Prof. Dr. Nikolaus Franke, wissenschaftlichem Leiter der TOP 100: “Die HOF Sonderanlagenbau GmbH ist konsequent und durchgängig auf Innovation ausgerichtet. Dies zeigt sich besonders bei der Außenorientierung, also bei der Art und Weise wie „open-innovation“ gelebt wird.“

HOF CryoBlizzard - a technology sets new standards

As an innovative market leader, HOF always puts emphasis on customer needs and market demands. Together with Mirai Intex (https://mirai-intex.com/de/startseite/) as a partner, the HOF CryoBlizzard has been developed as a new technology for our market segment.

A HOF freeze dryer from 1998 was retrofitted especially for this R&D project. The plant is a freeze dryer with a batch capacity of 40 kg for insulin production. Before this retrofit, refrigeration was achieved by two refrigeration sets, each containing 12 kg of the refrigerant R404A (GWP₁₀₀ = 3922). The process plant was controlled by a Siemens S5 control system.
 

Great performance with homogeneous temperature distribution

The overall retrofit has upgraded the lyo to a new refrigeration process, the HOF CryoBlizzard and to the current S7-1500 control system. With this new process, the refrigeration system consists of redundant cold air machines which are connected to a central primary tank in a modular system. The primary tank supplies the consuming units, such as shelf stack, ice condenser or blast freezer directly with the refrigerant medium and can therefore provide large capacities with homogeneous temperature distribution, all within a very short time. The usage of such a primary tank results in the fact that the consumption of cooling water and the power remain constant and no load peaks occur during the supply. Additionally, the cooling water consumption was reduced by half.
 

Air as refrigerant is free of charge and always available

The cold air machines from Mirai Intex are chillers which operate with air as a refrigerant using the Brayton cycle process. The maximum overpressure in the machines is 3 bar(a) and can be compared to that in a bicycle tire. This makes these machines particularly safe and environmentally friendly. Furthermore, no special requirements result in regards to the machine room set-up, employee training and recurrent testing. And in addition to all this, air as a refrigerant is free of charge and always available, has a GWP₁₀₀ value of 0 (zero) and is therefore not affected by any regulations.

“As an innovative equipment manufacturer, we knew thatwe have to come up with a new way forward - for our customers. The advantages of air as a refrigerant are obvious. Air is available, non-flammable, non-toxic and poses no risk of suffocation. Air has no GWP value and is therefore not subject to the F-Gas Regulation or any other directives. That is the future!”, says Oliver Fleischer from the refrigeration engineering and service management department at HOF.
 

The HOF CryoBlizzard turbocompressor, oil-free and almost wear-free

The refrigeration circuit is driven by an air-bearing supported, oil-free turbo compressor–expander unit that runs with up to 88000 rpm and virtually no wear. The refrigeration medium is cooled in a heat transfer unit, integrated into the chiller. The air that is heated this way, is aspirated by the turbocharger and compressed (steps 1 to 2). Subsequently, the energy in the gas chiller is dissipated to the environment and cooled down (steps 2 to 3). In an inner heat transfer unit, the recuperator, the air is strongly cooled down (steps 3 to 4) and then relaxed for effective use in the expander (steps 4 to 5). This work is returned to compression. The energy is now absorbed through heating of the air in the cold medium/heat transfer unit (steps 5 to 6). After the air in the recuperator has been heated again (steps 6 to 1), it is aspirated by the compressor and the cycle starts anew.
 

With HOF CryoBlizzard - renewing existing systems as a retrofit or implementing new systems

The modular design enables the capacity of the HOF CryoBlizzard to be scaled up or down as needed. This allos its adaption from small freeze dryer units all the way to a central cooling system for complete factories. Existing plants can be retrofitted and new plants can be implemented. With the HOF CryoBlizzard, HOF has developed a future-proof solution for freeze drying and blast freezing which is not only safe for employees and the environment, but also sets new standards with regard to the quality and availability of the application. Therefore, the HOF CryoBlizzard is another alternative technology by HOF to solve the GWP-issue of synthetic refrigerants in the long-run.

Sigraph announcement:

The CAE system SIGRAPH, used to create circuit diagrams until 2004, has already been discontinued by the manufacturer for some time. Economic processing of the circuit diagrams is therefore unfortunately no longer possible. We can therefore process changes in SIGRAPH diagrams only to a limited extent and must discontinue support for these circuit diagrams from 2022.

For larger modifications, we recommend converting the circuit diagrams to EPLAN P8.

EPLAN 5 announcements:

The CAE system EPLAN 5, used to create circuit diagrams between 2004 and 2016, has been replaced by the EPLAN P8 system. As of version EPLAN P8/2.8, EPLAN 5 can no longer run in a system environment. Furthermore, operation under Windows 10 is not released. However, support is still possible.
In the future, EPLAN 5 projects must therefore be migrated to P8 to enable further processing.

Bernd Becker (Head of Electronics Engineering)

"If modifications to your affected systems are planned, we will be happy to support you with a future-oriented solution."

HOF among TOP 100 companies again

398 companies entered the current round for a TOP 100 award.
TOP 100 uses a scientific system to evaluate the innovation management of SMEs.
This system, which was developed by Prof. Dr Nikolaus Franke, gives equal chances to manufacturing companies and service providers while also taking into account the respective size of the enterprises.
In this independent selection process, HOF and its 265 employees stood out in particular on account of its innovation success.

Finding innovative solutions – exploring new directions

For 30 years, the TOP 100 company has been specialised in the development and manufacturing of freeze drying systems, loading and unloading systems, and freezing and thawing equipment for the pharmaceutical industry. More than 2,000 systems in 27 countries prove the worldwide success of HOF.
Where bottles filled with frozen blood plasma used to be opened by people wearing gloves, this is now the task of a machine from the top innovator. The bottles are partially defrosted in an automatic process, opened with a so-called guillotine and then removed by robots for further processing of the plasma. The new innovative process from HOF is significantly faster and the system can operate around the clock.

“Being open to new things is a sign of a good innovation culture”

Physicist and scientific journalist Ranga Yogeshwar, who has been mentoring the competition since 2011, summarises the qualities of the TOP 100 as follows: “Being open to new things, tolerating mistakes, constantly striving to do things in a new and different way – those are the characteristics of a good innovation culture. A culture that is practised in the SMEs which we award with the TOP 100. They are exceptional medium-sized companies where the spirit of innovation has become part of their DNA. They are far-sighted, active entrepreneurs who focus on innovation every single day.” More information at www.top100.de.

HOF says thank you

“Receiving the award for the fourth time running makes us particularly proud.
We do not take it for granted and we will continue our endeavours to offer our customers the best, most innovative solutions.
But most of all, we want to thank our employees, without whom this success would not be possible.”
